scmutil: clean up bytes/string cache decorator mess on Python 3 again

The previous fix to this area worked, but was dropping bytes in
__dict__ on Python 3. This was causing subtle breakage in
test-check-interfaces.py, and probably other things too.

Fixed now.

# Dummy extension that adds a delay after acquiring a lock.
#
# This extension can be used to test race conditions between lock acquisition.
