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. (Bitbake rev: 12dc1d17fac3e8ec420fcafb06186d32fd847d89) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
