image_types: tar with --numeric-owner

If --numeric-owner is neither used when creating or extracting the archive
containing the rootfs then tar tries to change the numeric uid/gid of the
files based on user/group names of the host used to extract the archive.

Create the archive with --numeric-owner to remove the burden of having to
use --numeric-owner when extracting.
