socket-default: Use IPv6-only mode for IPv6 sockets

Browse Source 
Otherwise, we can't open a dedicated IPv4 socket on the same port as the
IPv6 socket already is set up do receive IPv4 packets (unless we'd again
enable SO_REUSEADDR).

Fixes: 83da13371292 ("socket-default: Don't set SO_REUSEADDR on IKE sockets anymore")
