fs: super_set_uuid()
Some weird old filesytems have UUID-like things that we wish to expose
as UUIDs, but are smaller; add a length field so that the new
FS_IOC_(GET|SET)UUID ioctls can handle them in generic code.

And add a helper super_set_uuid(), for setting nonstandard length uuids.

Helper is now required for the new FS_IOC_GETUUID ioctl; if
super_set_uuid() hasn't been called, the ioctl won't be supported.
