Brad Fitzpatrick d8a531108d wgengine/magicsock: quiet an IPv6 warning in tests
In tests, we force binding to localhost to avoid OS firewall warning
dialogs.

But for IPv6, we were trying (and failing) to bind to 127.0.0.1.

You'd think we'd just say "localhost", but that's apparently ill
defined. See
https://tools.ietf.org/html/draft-ietf-dnsop-let-localhost-be-localhost
and golang/go#22826. (It's bitten me in the past, but I can't
remember specific bugs.)

So use "::1" explicitly for "udp6", which makes the test quieter.
