For stable branches, we currently only check out the correct mutter
branch for merge requests. For the regular pipeline, our code to
determine the current shell branch fails because CI runs on a
temporary "pipeline/12345" branch that doesn't exist for mutter.
Switching to the correct gitlab environment variable fixes that.

Depending on how gitlab's CI checks out gnome-shell, the shell branch
may not have a local reference like "gnome-3-32", but only a remote
one like "remotes/origin/gnome-3-32".
Consider that case as well when looking for a corresponding mutter branch.

If we don't find a branch that matches the branch used in the merge
request, we currently fall back to the non-merge-request matching,
i.e. first try the current shell branch, then fall back to master.
This should work for commits to upstream branches, but not for merge
requests to a stable branch. For those, the target branch name is
a better fallback.

So far we are only performing a basic syntax check on javascript
sources; it's time to test the C code as well. As mutter is tightly
coupled, we bite the bullet and build it as well, either using a
matching branch (if it exists), or current master.
