bitbake: runqueue: Fix sstate task dependency problems

If a setscene task has [depends], its possible they may still get executed out
of order. The issue is that the dependencies are set to set() for all tasks
involved. This patch adds back in explict dependencies within these chains
to avoid the setscene task failures.
