GFS2: Remove mount.gfs2 and its man page from gfs2-utils
    
    The mount.gfs2 binary is not required for recent kernels and
    has been optional for a while. The plan is to no longer include
    it in rawhide. When all versions of Fedora no longer have mount.gfs2
    (i.e. when F14 is EOL) then mount.gfs2 will be removed from the
    upstream source.
    
    Do not pull this change into earlier versions of Fedora since those
    may have kernels without all of the support required for this
    feature.
