dpif: Always generate RFC4122 UUIDs for UFID.

This patch sacrifices a few bits of hash quality from the 128-bit unique
flow identifiers to make the UFIDs RFC4122-conformant as per the version 4
(random) UUID spec. Given that the 128-bit space is already quite large,
this should not affect the spread of UFIDs in any meaningful way for
hashing.
