bitbake: bitbake-diffsigs: make finding of changed signatures more robust

Browse Source 
In `runtaskhashes`, the keys contain the absolute paths to the recipe. When
working with shared sstate caches (where these absolute paths can be different)
we see that compare_sigfiles does not identifiy a changed hash of a dependent
task as "changed", but instead as "removed"&"added", preventing the function
from recursing and continuing the comparison.

By calling `clean_basepaths` before comparing the `runtaskhashes` dicts, we
avoid this.
