8e729d511e units: update catalog after systemd-tmpfiles runs
`systemd-journal-catalog-update.service` writes to `/var`. However, it's
not explicitly ordered wrt `systemd-tmpfiles-setup.service`, which means
that it may run before or after.

This is an issue for Fedora CoreOS, which uses Ignition. We want to be
able to prepare `/var` on first boot from the initrd, where the SELinux
policy is not loaded yet. This means that the hierarchy under `/var` is
not correctly labeled. We add a `Z /var - - -` tmpfiles entry so that it
gets relabeled once `/var` gets mounted post-switchroot.

So any service that tries to access `/var` before `systemd-tmpfiles`
relabels it is likely to hit `EACCES`.

Fix this by simply ordering `systemd-journal-catalog-update.service`
after `systemd-tmpfiles-setup.service`. This is also clearer since the
tmpfiles entries are the canonical source of how `/var` should be
populated.

For more context on this, see:

73c729d768 units: fix condition for systemd-journal-catalog-update.service (#4990)
The service is supposed to regenerate the catalog index whenever /usr is
updated, but /var is not. Hence the ConditionNeedsUpdate= line should
actually reference /var, as that's where the index file is located.

75f709fbf2 units: so far we defaulted to 90s as default timeout for most things, let's do so for our oneshot services too
Fewer surprises, and stuff...

0775b9b611 units: set TimeoutSec on some oneshot services
Services which are not crucial to system bootup, and have Type=oneshot
can effectively "hang" the system if they fail to complete for whatever
reason. To allow the boot to continue, kill them after a timeout.

In case of systemd-journal-flush the flush will continue in the background,
and in the other two cases the job will be aborted, but this should not
result in any permanent problem.

b63bb8a724 units: drop RefuseManualStart= from a couple of update services
The only update service we really need to guard like this is
systemd-tmpfiles-setup.service since if invoked manually might create
/var/run/nologin and thus blocking the user from login. The other
services are pretty much idempotent and don't suffer by this problem,
hence let's simplify them.

ecde7065f7 units: rebuild /etc/passwd, the udev hwdb and the journal catalog files on boot
Only when necessary of course, nicely guarded with the new
ConditionNeedsUpdate= condition we added.
