gitlab CI: add support for DRM-backend tests

In order to run DRM-backend tests, a DRM-device is needed. As we
do not necessarily have control of the hardware that is going to
run our tests in GitLab CI, DRM-backend tests were being skipped.
This patch add support to run the tests using VKMS (virtual KMS).
To achieve this, virtualization is needed, as we need to run a
custom kernel during the CI job. We've decided to go with virtme,
as it is simpler to setup and works good for our use case.

# Link to upstream virtme: https://github.com/amluto/virtme
#
# The reason why we are using a fork here is that it adds a patch to have the
# --script-dir command line option. With that we can run scripts that are in a
# certain folder when virtme starts, which is necessary in our use case.
#
# The upstream also has some commands that could help us to reach the same
# results: --script-sh and --script-exec. Unfornutately they are not completely
# implemented yet, so we had some trouble to use them and it was becoming
# hackery.
