debian-testing is the critical path: the shortest possible job to build
exactly what we need to execute on hardware, and nothing else.
debian-build-testing exists to give us better coverage at the expense of
running longer.
Since the only jobs using r300 and Nine, and the only jobs using NVK,
are in post-merge stages which are manually triggered, move these builds
to debian-build-testing. This makes the critical path to those a little
longer, but we do get to make it shorter for everyone else just running
regular Marge jobs.
