icmpv6: Allow matching target address in NS/NA, redirect and MLD
It was currently not possible to match the target address of a neighbor
solicitation or neighbor advertisement against a dynamic set, unlike in
IPv4.
Since they are many ICMPv6 messages with an address at the same offset,
allow filtering on the target address for all icmp types that have one.
While at it, also allow matching the destination address of an ICMPv6
redirect.
