Subject: [PATCH] kernel: Skip ipv6 tcs when cpiv6 is disabled

For some reason doing a gen_udp:open(0, [inet6,{ipv6_v6only,true}])
works on some systems where ipv6 is disabled. So instead we
explicitly require the localhost ip to do the test at which seems
to work better.

ipv6 was disabled in sysctl using the line net.ipv6.conf.all.disable_ipv6=1
when this behaviour was found.
