    Allow GParted to read the UUID from older btrfs-show command
    
    All the code was there in btrfs::read_uuid() to read the UUID from the
    btrfs-show command.  It just needed enabling.
    
    This is only relevant when: (1) the blkid command is unavailable as
    GParted primarily reads the UUID through the FS_Info cache using the
    blkid command, and (2) the btrfs command is unavailable and the btrfs
    module uses the older btrfs-show command instead.
