Don't allow creating a socket with a protocol family that the current
jail doesn't support.  This involves a new function prison_check_af,
like prison_check_ip[46] but that checks only the family.

With this change, most of the errors generated by jailed sockets
shouldn't ever occur, at least until jails are changeable.
