test/py: Rework test_xxd to not use virt-make-fs
The problem with using "virt-make-fs" to make a filesystem image is that
it is extremely slow. Switch to using the fs_helper functions we have
instead from the filesystem tests as these can add files to images and
are significantly faster and still do not require root access.
