libxtables: store all requested match types

iptables and ip6tables don't need this because iptables is AF_INET,
ip6tables AF_INET6, etc.

But tools that can change af in-between such as nftables will then
may then find to find such module.

One example is conntrack, it offsers NFPROTO_IPV4 and NFPROTO_IPV6.
When first loading with NFPROTO_IPV6, the IPV4 would be discarded.
