Use proto_to_name() from xshared in more places
Share the common proto name lookup code. While being at it, make proto
number variable 16bit, values may exceed 256.
This aligns iptables-nft '-p' argument printing with legacy iptables. In
practice, this should make a difference only in corner cases.
