bitbake: runqueue: Add further debug for sstate reuse issues

Even after enabling all our debugging, we had a reproducible test case
where sstate wasn't being reused and it was unclear from the logs why.

This patch adds debugging on the possible codepaths that were breaking
and allowed the issue to be debugged and fixed.
