lib: treat OSX as BSD for IP_HDRINCL (BZ#739)

Mac OS X needs HAVE_IP_HDRINCL_BSD_ORDER defined like BSD. If it's not
defined, it'll fail like this:

  *** sendmsg in ospf_write failed to 224.0.0.5, id 0, off 0, len 64,
  interface en0, mtu 1500: Invalid argument

Which is caused by reordering iph->ip_len in
sockopt_iphdrincl_swab_htosys.
