examples/inet/ipsec: IPv6 multicast BYPASS config + fingerprint

Add [Config Multicast6] to ipv6.ini: a UDP stream to an IPv6 global-scope
multicast group (ff0e::8). IPsec lets it pass unprotected -- the egress hook
short-circuits to BYPASS on a multicast destination (getRemoteAddress()
.isMulticast()) before any SPD lookup -- and it is delivered end to end to the
joined UdpSink. Records the tplx;~tNl fingerprint (6/6 ipsec rows pass).
