blkid: more sanity checks for swap v1

mkswap followed by pvcreate on a block device
will still turn up as "swap" in blkid, because
pvcreate isn't particularly careful about zeroing
old signatures.  (neither is mkswap, for that matter).

Testing for appropriate version and page counts
gives us a bit more confidence that we have a
real swap (v1) partition.
