udevadm: prevent segfault in blkid builtin when offset not specified

"--offset" takes an optional argument; if none is specified,
stroull() will attempt to parse a NULL pointer. For example:

$ udevadm test-builtin 'blkid --offset' /sys/dev/block/8:1

Update "--offset" to require an argument; also verify that the
offset is not negative.
