[socket-nif] Conditional use of sctp struct field

Added config checks for the sctp struct field:

    sctp_event_subscribe.sctp_authentication_event

Also, if-def'ed the code accordingly.

If-def'ed code to handle the (non-) existence of IP_PMTUDISC_PROBE
and IPV6_PMTUDISC_PROBE for the IP and IPv6 MTU_DISCOVER options.
