Subject: libblkid: merge FS* flags into one FSINFO
Put BLOCK_SIZE, FSSIZE and FSLASTBLOCK tags under one FSINFO flag.
These, and probably future ones, are read directly from the
superblock (with minor post-processing). These properties are
combined under one flag to escape adding a flag per superblock
member.
