Improve VFAT detection to support filesystems w/o a magic string in the superblock

The current libblkid code expects that there's magic string in FAT super
block (like "FAT12", "FAT16", ...). It's very often right, but valid FAT
super block may be without magic string too :-(

The patch from attachment fix this problem. It's inspired by HAL and
Linux kernel.
