GFS2: Expose UUID via sysfs/uevent
Since we have a UUID, we ought to expose it to the user via sysfs and uevents. We already have the fs name in both of these places (a combination of the lock proto and lock table name) so if we add the UUID as well, we have a full set. For older filesystems (i.e. those created before mkfs.gfs2 was writing UUIDs by default) the sysfs file will appear zero length, and no UUID env var will be added to the uevents.
