When accessing journal files we generally are fine when values change
beneath our feet, while we are looking at them, as long as they change
from something valid to zero. This is required since we nowadays
forcibly unallocate journal files on vacuuming, to ensure they are
actually released.
However, we need to make sure that the validity checks we enforce are
done on suitable copies of the fields in the file. Thus provide a macro
that forces a copy, and disallows the compiler from merging our copy
with the actually memory where it is from.
The setup is meant to run against openSUSE Tumbleweed and install
minimum packages necessary for successful build and passing tests.
To speed up incremental build an external build directory is used.
Otherwise we'd not read the services input while waiting for the job to
wait, and there's no point in waiting for the job anyway if we wait for
the unit to stop ultimately.

Let's add flavours for copying stub/uplink resolv.conf versions.
Let's add a more brutal "replace" mode, where we'll replace any existing
destination file.
Let's also change what "auto" means: instead of copying the static file,
let's use the stub file, so that DNS search info is copied over.

When a job is skipped due its dependencies not being ready, log
a debug message saying what is holding it back.
This was very useful with transient units timing out to figure
out where the problem was.
Some testcases in test-execute rely on existence of user groups with
certain gids. However, their existence is not universally granted [1].
Although the test could be skipped in their absence and give up testing
some code paths, different approach was chosen -- create dummy groups in
the testing image.
[1] See how systemd-sysusers allocates gids (e.g.
src/test/test-uid-range.c).
Distributions may be build with various configs, e.g. customized
rootprefix. It'd be unmaintanable to have specific mkosi.build for each
supported distro. Hence, make the build script flexible yet distro
oblivious.
Remove the artifact files indicating test result (testok, failed, and
skipped) just before running the test so we always get the latest and
most relevant result instead of incorrectly consuming previous results.

Anyone previously using the UseRoutes=false parameter expected their
dhcp4-provided gateway route to be ignored, as well. However, with
the introduction of the UseGateway= parameter, this is no longer true.
In order to keep backwards compatibility, this sets the UseGateway=
default value to whatever UseRoutes= has been set to.
The disk attributes can take some time to update on certain filesystems,
so let's strip them from inputs of both `homectl` and `userdbctl` before
comparing them to avoid unexpected fails.
Also, switch from `cmp` to `diff` to make a potential test fail a bit more
debuggable.
