Set root password with guestfs-python

Use the python bindings of libguestfs to create additional qcow2 image
which has as backing file the last layer (layer-0.qcow2 for FileSource)
and insert hashed value of given root password in the /etc/shadow file.

Note: This additional qcow2 image is also used to apply UID/GID map.
