dunfell: remove .py files from rootfs
Only the .pyc files are needed so save some space in the image by
removing the .py files.
With the move to python3, machines that bring python into their image no
longer build due to the squashfs being too large. This fixes that issue.
A similar function as this used to be under the tiny-distro feature but
it just needs to be mandatory now until someone feels like they need
the .py files in the image.
