libuuid: fix name-based UUIDs
The current version is not fully compatible with RFC4122. It
incorrectly encodes UUID variant
xxxxxxxx-xxxx-Mxxx-Nxxx-xxxxxxxxxxxx
where M is UUID version and N is UUID variant.
$ python -c "import uuid ; print(uuid.uuid5(uuid.UUID(int=0), 'foo'))"

Old version:
$ uuidgen --namespace 00000000-0000-0000-0000-000000000000 --name 'foo' --sha1

Fixed version:
./uuidgen --namespace 00000000-0000-0000-0000-000000000000 --name 'foo' --sha1;

The patch uses uuid_unpack and uuid_pack. It makes code more readable
and allow to access proper octens. The same way we already use for
time and random based UUIDs.
