This drops logs of failed unit tests in TEST-02-UNITTESTS from the journal,
as the expected logs from test-varlink-idl makes the post script fail.
Saving logs in journal is simply noisy, and we will output anyway after
qemu or nspawn finished by check_result_{qemu,nspawn}_unittests().
The test was originally introduced for Ubuntu CI, as it uses
PREFER_NSPAWN=1, but it was subsequently disabled two years ago [0], so
it was pretty much useless. Let's merge it into TEST-02 and tweak it a
bit to run only certain tests under QEMU when $TEST_PREFER_NSPAWN is
set.

The kernel command line may contain newlines which kernel happily
accepts, but we'd ignore everything past the first newline. Let's fix
that by replacing read_one_line_file() with read_full_file().
When the interpeter is missing, we get an exit code of 127. Let's treat those
tests as skipped too. If we could run the test far enough so that it could do
the check itself, it would return 77 anyway.
$ test/asdf; echo $?
exec: Failed to execute process 'test/asdf': The file specified the interpreter '/bin/asdf', which is not an executable command.
127
$ test/asdf; echo $?
/usr/bin/env: ‘/bin/asdf’: No such file or directory
127
This should resolve the problem that TEST-02 fails or Debian's 'unit-tests' fail
when python3 is not installed. Installing python3 via the mechanism that is
used to construct TEST images, i.e. the dracut dependency chasing scheme, would
be a lot of work for python with its modules in multiple locations and hundreds
of little files. So I think it OK to just skip the test there, and also in
other cases where python is not available.
/usr/lib/systemd/tests may contain more than the unit tests. For example on
SUSE we also install the integration tests there.
Putting the unit tests in a dedicated directory named 'unit-tests' makes the
layout cleaner.
Note that `run-unit-tests.py` has not been moved so we don't need to adjust
(Fedora) packaging and users also don't need to descend into the subdirectory.
When tests are executed serially (the default), it seems better to launch
the fairly generic test that runs the unittests early in the sequence.
Right now the tests are ordered based on when they were written, but
this doesn't make much sense.
