bitbake-diffsigs: break on first dependent task difference
compare_sigfiles() recursively calculates differences on all dependent tasks with changed hashes. This is done in arbitrary/alphabetical order, and only the last of those results is returned, while everything else is discarded. This changes the behavior to instead return the first difference and not calculate any more, which significantly speeds up diffs of tasks with many dependencies.
