9f2db12329 core: Fix fcaps (e.g. ping) in unified core mode
This fixes another thing broken with `compose --ex-unified-core`;
for e.g. `/usr/bin/ping` from `iputils`, the classic example of a filecaps
binary.

As I'm writing this commit message I realize it will actually also
take effect for package layering unnecessarily; we'll pointlessly
break the hardlink.  But eh, it doesn't matter right now, we can
optimize that later.

6a2962fd8b core: Process systemctl preset in %post
Rather than entirely symlinking `systemctl` → `/bin/true`, in order
to e.g. have NetworkManager be enabled, we need to process presets.

This is one of the things that's breaking FAHC where I did a
`--ex-unified-core` deployment.

(Actually it's a bit tempting to run a mass preset pass at the end,
 but for now let's do this)

Implementation note: this is our first use of GResources, which
is a handy way to embed data into our final binary.

879c5afefc compose: Write rpmdb to /usr/lib/sysimage/rpm-ostree-base-db
This is prep for a rework of
https://github.com/projectatomic/rpm-ostree/pull/621

For a no-op `rpm-ostree upgrade` (i.e. no updates available), as long as
layering is enabled, we pay the cost of checking out the base tree, *mostly*
only to get the base rpmdb.

This is prep for fixing that down the line by knowing we always have the "base"
tree's rpmdb checked out. Then in the layering case we only modify
`/usr/share/rpm` (eventually that will point to `/usr/lib/sysimage/rpm`).

Teaching `rpmostree-core.c` about this can follow on later.

802c1fcb90 compose: Fix --ex-unified-core devino cache (suid bits lost)
With unified core 🌐 we are *relying* on the devino cache
for correctness when using `bare-user` repos.  Otherwise lots
of bad things will happen as we won't hit the happy path from
[this libostree PR](https://github.com/ostreedev/ostree/pull/1297)
(I should probably add an assertion there that we aren't trying to commit
 `user.ostreemeta`).

It looks like I had this working in some of the old unified core WIP patches,
but it was lost when rebasing 🏄.

We noticed this when I was trying to deploy jigdo in FAHC and the system
wouldn't boot as various things rely on those suid transitions.

752166ce3b app/compose: include rpmdb pkglist in compose
We don't want to have to download all of `/usr/share/rpm` just to get
the list of packages used to compose the tree. This is fundamental
information that needs to be easier to discover. So let's stick it right
in the commit metadata. There's various use cases for this information,
including easily checking for and displaying updates and a pkglist-aware
version of `ostree log`.

6bf4206223 compose: Add --ex-unified-core
The "--ex" prefix here means it's an experimental option. A tremendous change
here is that start to support non-uid 0, but there are various things to fix there;
the unpacker for example needs to learn to set imported objects fully based
on the rpmfi information (i.e. default to uid 0, since libarchive gives the
current uid by default).

And even when run as uid 0, there are some bugs, though I'm not sure
of any showstoppers yet.  For example, dracut's `dracut-install` calls
`cp --preserve=xattrs` which fails to copy the `user.ostreemeta` xattrs
from a checkout (it shouldn't be copying that anyways...)

Nevertheless, the infrastructure behind this really helps (is almost a hard
requirement for) the [jigdo effort](https://github.com/projectatomic/rpm-ostree/issues/1081).
Which is really only true due to SELinux - we need to import the packages,
then generate the final tree to get the final policy, then use that policy
to relabel all of the packages.
