unix: add functions to encode Inet4Pktinfo and Inet6Pktinfo

It's possible to control the source address of a UDP packet by
passing a socket control message of type IP_PKTINFO or IPV6_PKTINFO.
This is a somewhat esoteric feature of the network stack, but it's
extremely useful feature when you really need it.
