Rather than use the round-robin mirror, use a fixe stable one.
We should not over-use this, but it seems the round-robin one is
simply too unstable for our tests.
Eventually, we want to use metalink here instead, but we need to
rework the file source first, so we can do that in a way that
does not make the tests dependent on the time/place the test
case was generated (currently the URL to a specific mirror ends
up pinned in the test-case).

This means that the unit tests no longer need to load the
repositories from the git repo, and in a follow-up, osbuild-composer
won't need to either.
By splitting the repositories used for testing from the system
repositories available through the weldr API we are able to extend
the system repositories without affecting the reproducibility of
the tests.
