Paul Sokolovsky d21d029d55 py/mkrules.mk: Add "clean-frozen" target to clean frozen script/modules dir.
This target removes any stray files (i.e. something not committed to git)
from scripts/ and modules/ dirs (or whatever FROZEN_DIR and FROZEN_MPY_DIR
is set to).

The expected workflow is:

1. make clean-frozen
2. micropython -m upip -p modules <packages_to_freeze>
3. make

As it can be expected that people may drop random thing in those dirs which
they can miss later, the content is actually backed up before cleaning.
