Allow sockaddr_ntop() to format AF_UNSPEC socket addresses. There do exist
a few cases where we might legitimately have either an AF_UNSPEC or a real
address, such as the origin address from MSG_ERRQUEUE. Even in cases where
we shouldn't get an AF_UNSPEC address, formatting it is likely to make
things easier to debug if we ever somehow do.
