volume_id: enable GFS probing code, add LABEL support
* enables GFS/GFS2 probing code (it's disabled now!)
* adds support for LABELs -- it seems that locktable name is usable as
a LABEL (at least according to libblkid).
* removes extra check of sb_header.mh_format -- nothing in kernel and
blkid checks this superblock entry. It seems that check GFS_MAGIC and
GFS_METATYPE_SB is enough.
