inet_drv.c: Set sockaddr lengths in inet_set_[f]address
Set appropriate values for the sockaddr length fields---sai.sin_len
and sai6.sin6_len---if those fields exist; rely on the NO_SA_LEN
configure check to see if they exist. The length field exists on at
least FreeBSD, and there it needs to have a proper value for instance
in the call to sctp_bindx, or else that will fail with EINVAL.
