Justification: fails to build from source (but built successfully in the past)
mutter failed to build from source on several architectures, including
'all', with this failure in the
"mutter:clutter+clutter/conform / timeline" test-case:

If this is operating in real-time, then I think this test might need
to be disabled or marked as flaky for buildd purposes: on an un-loaded
developer machine with a real GPU and other nice amenities, we might be
able to assert that the deadline for a frame is never missed, but on a
buildd that is set up for batch processing, rendering in software and
potentially running other things in parallel, I don't think that assertion
is realistic.
It might also be pragmatic to disable the tests when we are only doing
an Architecture: all build (like we do in glib2.0), so that those always
succeed, even if some builds for specific architectures fail.
