bitbake: runqueue: Fix deferred task issues

Browse Source 
In a multiconfig situation there are circumstances where firstly, tasks
are deferred when they shouldn't be, then later, tasks can end up as
both covered and not covered.

This patch fixes two related issues. Firstly, the stamp validity checking
is done up front in the build and not reevaulated. When rebuilding the
deferred task list after scenequeue hash change updates, we need therefore
need to check if a task was in notcovered *or* covered when deciding to
defer it. This avoids strange logs like:

NOTE: Running setscene task X of Y (mc:initrfs_guest:/A/alsa-state.bb:do_deploy_source_date_epoch_setscene)
NOTE: Deferring mc:initrfs_guest:/A/alsa-state.bb:do_deploy_source_date_epoch after mc:host:/A/alsa-state.bb:do_deploy_source_date_epoch

where tasks have run but are then deferred.

Since we're recalculating the whole list, we also need to clear it before
iterating to rebuild it. By ensuring covered tasks aren't added to the
deferred queue, the covered + notcovered issue should also be avoided.
in the task deadlock forcing code.
