Update Python3 bytecode timestamps

#!/usr/bin/python3
# Python scripts which reads all Python bytecode files (pyc) and clears
# the timestamp (set to 0)
# This is useful for OSTree which clears modification time of all source
# files. Processed bytecode files are then not considered stale anymore.
