[PATCH v2 0/4] Test more in less time in the Gitlab-CI

[Thomas Huth <thuth@redhat.com>]

This patch series adds two new "build-system" pipelines to the Gitlab-CI,
one based on Debian and one on CentOS. We then use these build pipelines
to test the targets that were missing so far (e.g. the two new targets
rx-softmmu and avr-softmmu), and move some of the targets from the other
build-system pipelines here, too, so that the total testing time gets
shorter (at least 5 minutes from what I've seen so far).

Unfortunately, two of the avocado-based acceptance tests that would get
enabled by this are not working on gitlab, so they are disabled in the
second patch. It does not seem to be a caching issue (I've checked it
with the fourth patch), maybe it's something related to ports not being
available in the container, but I did not investigate further. They
can be enabled back later again when someone has some more time for
debugging.

v2:
 - Added Reviewed-bys from v1
 - Added fourth patch to fix the caching issue
