Fix SCTP support on FreeBSD & NetBSD

Browse source 
Unlike Linux, Solaris, and Illumos (and probably others), the 2 BSDs that still
support SCTP didn't put SCTP into its own library, they put it into libc.

They, unlike Linux, don't set SOL_SCTP for us. The official method appears to
be calling getprotobyname("sctp") & endprotoent(), with getprotobyname()
returning a struct that has a p_proto entry. This all reads from
/etc/protocols. However, SCTP is assigned 132 by IANA, so it's 132 everywhere,
so I just set SOL_SCTP to 132 if it's not already set.
