test: skip IPv6 test on non-IPv6 systems

Trott · Italo A. Casas · commit 7fb4e297e660 · 2017-02-21T14:54:10.000-05:00
Until recently, test-dgram-address would fail on machines without IPv6 but still exit with a successful return code. (It would console.log() the error but not actually fail.) Now that the test has been updated such that it will fail the IPv6 part of the test if there is an error event emitted by the socket, skip the test on systems not equipped with IPv6.
