bitbake: runqueue: Improve scenequeue debugging

Whilst we had good runqueue failure mode debug, it hadn't adapted to the
scenequeue changes. Run the scenequeue sanity tests at the end of
a build and output the results regardless of whether all setscene tasks
completed or not. This *massively* improves the ability to debug runqueue
problems.
