Apply ratbox3 workaround for too permissive inet_pton6():

Any kline (or various other things) containing * or ? is
a mask kline and not an IP kline. Ideally, rb_inet_pton_sock()
would return failure for those, but in practice this is not
always the case for IPv6.

Such a kline that is erroneously treated as an IP line
likely matches way fewer IPs than expected.
