Patrick Ohly 937c1ea974 yocto-compat-layer: include bitbake-diffsigs output
After filtering out potential false positives, it becomes feasible to
include the output of bitbake-diffsigs for those tasks which
definitely have a change.

Depends on bitbake-diffsigs with the "--signature" parameter.

Enhanced output now is:

   AssertionError: False is not true : Layer meta-xxxx changed 120 signatures, initial differences (first hash without, second with layer):
