Add the neccessary sockopts for ping and traceroute on IPv6.
This fixes the following qemu warnings with IPv6:
Unsupported ancillary data: 0/2
Unsupported ancillary data: 0/11
Unsupported ancillary data: 41/25
Unsupported setsockopt level=0 optname=12
Unsupported setsockopt level=41 optname=16
Unsupported setsockopt level=41 optname=25
Unsupported setsockopt level=41 optname=51
Unsupported setsockopt level=41 optname=8
Unsupported setsockopt level=58 optname=1
Tested on hppa-linux-user.
