bitbake: bitbake-diffsigs: allow specifying task & follow deps recursively
Add the ability to compare the two most recent runs of a specified task,
and follow dependent hash changes recursively. This enables you to trace
back and find exactly why a task was re-run after the fact.
Note that this relies on the metadata providing a function, hooked in
as bb.siggen.find_siginfo, which allows searching in the appropriate
places to find signature data files.
