Fixes the following unexpected skip:

```
Having these named differently than the test itself mostly creates
unecessary confusion and makes writing logic against the tests harder
so let's rename the testsuite-xx units and scripts to just use the
test name itself.
Recent lcov started complaining loudly about unknown lines in gperf

Use 'geninfo --filter range' to remove out-of-range lines.
(use "geninfo --ignore-errors range ..." to bypass this error)
Since we drop the coverage of built files from the final report anyway,
let's do it also when capturing both initial and real coverage to avoid
this error.
This commit adds definitions to build the minimal_0 and minimal_1
images with mkosi and includes them into the system image. We also
move the building of the various app-xxx and similar images that are
extremely minimal into the tests itself by moving the related logic
from install_verity_minimal() into a new function
install_extension_images() in util.sh. Because the mkosi /usr is
read-only, we now place the extension images in /tmp instead of
/usr/share.

The logs from TEST-69 still contain a lot of unnecessary shell
metacharacters, so to make the output more readable let's just set
TERM=dumb, instead of having to strip everything semi-manually. Also,
move the related --background= tweak to TEST-69, since it's relevant
only for that particular test.

gcrypt is used only for journal sealing operations in libsystemd, so it
can be made into a dlopen dependency that is used only on demand. This
allows to reduce the footprint of libsystemd in the most common cases.
Keep systemd-pull and systemd-resolved with normal linking, as they are
executables, and usually built with OpenSSL support anyway.
Private images are not reused, they are unique to tests, so delete them
as they take a lot of disk space, and we are starting to run in /var/tmp
space issues on the Ubuntu CI
There's something very wrong going on when using btrfs for the test
images, namely:
- there's a significant performance hit, i.e. the Arch Linux run is
~20% slower, in the coverage run the situation is even worse
- intermittent boot failures
- intermittent "No space left on device" errors (even though there's
enough free space)
Since debugging this might take a while, let's temporarily revert back
to ext4 to make the CI stable again.
This reverts commit 7eb7e3ec4f5dbc13ee729557e1544527f3101187.
Othewise test images are missing the tmpfiles snippets used to create the very
basic files at boot, which can be useful when a test wants to reuse the OS tree
(is already running in) for spawning a new container in pristine state.
Arch finally made dbus-broker the default dbus daemon [0], but unlike
Fedora they don't use Alias=dbus.service to make the dbus.symlink under
/etc, instead they create the symlink manually under /usr/lib, so let's
account for that.

If a binary built with ASan crashes for a reason unrelated to ASan
stuff, we're left with pretty much nothing, as there is neither an ASan
trace nor a coredump. Let's make this slightly more debug-able by
allowing such binaries to dump a core, but without the huge shadow map
(we should be actually fine by just setting disable_coredump=0, since
use_madv_dontdump defaults to true, but let's play it safe and not
potentially dump a 16+ TB core file).
We can't use the systemd-journal-upload user here, since it's created
dynamically by DynamicUser=yes. However, we can use the group specified
in SupplementaryGroups=, so do exactly that.
Turns out that redirecting a lot of output to the console can have some
funny effects, like random kernel soft lockups. I spotted this in
various CIs, but it remained almost entirely hidden thanks to
`softlockup_panic=1`, until 1a36d2672f which introduced a couple of
tests that log quite a lot in a short amount of time. This, in
combination with newer kernel version, which, for some reason, seem to
be more susceptible to such soft lockups, made the Arch Linux jobs soft
lockup quite a lot, see [0].
While debugging this I also noticed that runs which don't redirect
stdout/stderr to the console are noticeably faster, e.g.:
# TEST-71 nspawn + QEMU (KVM), StandardOutput=journal+console
Elapsed (wall clock) time (h:mm:ss or m:ss): 0:24.64
# TEST-71 nspawn + QEMU (KVM), StandardOutput=journal
Elapsed (wall clock) time (h:mm:ss or m:ss): 0:17.95
# TEST-71 nspawn + QEMU, StandardOutput=journal+console
Elapsed (wall clock) time (h:mm:ss or m:ss): 2:04.70
# TEST-71 nspawn + QEMU, StandardOutput=journal
Elapsed (wall clock) time (h:mm:ss or m:ss): 1:44.48
# TEST-04 QEMU, StandardOutput=journal+console
Elapsed (wall clock) time (h:mm:ss or m:ss): 4:22.70
# TEST-04 QEMU, StandardOutput=console
Elapsed (wall clock) time (h:mm:ss or m:ss): 5:04.67
Given all this, let's effectively revert ba7abf79a5, and dump the
testsuite-related journal messages only after the test finishes, so they
don't go through the slow console.

Let's save all journals from the test machine instead of calling export
on each journal file separately, which makes the code less complicated
(and probably faster).
I'm pretty sure this is not the only case, but it's the one I recently
noticed. Even though we call ddebug() from a function, that function is
called before ddebug() is defined, resulting in the same issue as if we
called just ddebug() in its place, i.e.:
..//test-functions: line 276: ddebug: command not found
