siggen.py: Fix diffsigs output for filename comparisions

When comparing sig files, if the recipe locations had changed, the
dependent tasks list would show as changed even if the actual hash
had not changed. This updates the code to only compare the base part
of the pathnames.

It also tweaks some of the output to add newlines to aid comparing
two lists of variables as it makes the location of the difference
clearer.
