async_hooks,test: only use IPv6 in http test

AndreasMadsen · apapirovski · commit b12425d055f3 · 2018-01-14T12:31:56.000-05:00
If IPv6 is not supported on a machine, the IPv6 handle will first be created, this will then fail and default to an IPv4 handle. This causes the graph to change, as there now is an extra handle.
