Activate the new python rootfs/image creation routines

This commit will:
 * remove old bash code common to all backends;
 * create a new do_rootfs() python function that will use the new
   rootfs/image creation routines;
 * allow creation of dpkg based images;
 * fail for rpm/opkg (not implemented yet);
