libxtables: avoid confusing use of ai_protocol=IPPROTO_IPV6
[Split hunk from Wes's submission. Added commit message. -j.eng] ai_protocol normally specifies the L4 protocol one wants to specifically inquire about when a service (2nd parameter to getaddrinfo) is specified. Such a service lookup would potentially yield nothing, because there just is not any "mytunnel 2222/ipv6" in /etc/services, since IPPROTO_IPV6 itself is not a protocol with a concept of (port-based) services to begin with.
