yocto-compat-layer.py: apply test_signatures to all layers

Software layers were previously allowed to change signatures, but
that's not desired for those layers either. The rule that a layer
which is "Yocto Compatible 2.0" must not change signatures unless
explicitly requested holds for all kinds of layers.

However, as this is something that software layers might not be able
to do right away, testing for signature changes in software layers can
be disabled. It's on by default, as that was Richard's
recommendation. Whether that should change needs further discussion as
part of finalizing "Yocto Compatible 2.0".

As it might still change, the tool now has both a with/without
parameter so that users of the tool can choose the desired behavior
without being affected by future changes to the default.
