bitbake: runqueue: Fix task weighting algorithm

When looking at a list of tasks, do_patch and do_unpack were being
given equal priority when one clearly depends on another. The
reason for this was the default task weights of 0 being to tasks.
This is therefore changed to 1 to allow correct weighting of dependencies
which means the scheduler has better information available to it about
tasks.

Weight endpoints differently (10) for clearer debugging of priorities.
