Currently, the ubifs-in-ubi-image ("UBI image" thereafter) filesystem
is half an option of the ubifs filesystem, half a filesystem on its
own: the config options are options of the ubifs filesystem, but the
.mk code is in a separate .mk and registers a real filesystem.
Make it a full filesystem on its own, in its own directory tree.
