Disable PMTUDiscovery in switch and hub modes.

In switch and hub modes, tinc does not generate ICMP packets in response to
packets that are larger than the path MTU.  However, if PMTUDiscovery is
enabled, the IP_MTU_DISCOVER and IPV6_MTU_DISCOVER option is set on the UDP
sockets, which causes all UDP packets to be sent with the DF bit set, causing
large packets to be dropped, even if they would otherwise be routed fine.
