Josh Bleecher Snyder 6e8328cba5 wgengine/tsdns: replace connections when net link changes (macOS)

When the network link changes, existing UDP sockets fail immediately
and permanently on macOS.

The forwarder set up a single UDP conn and never changed it.
As a result, any time there was a network link change,
all forwarded DNS queries failed.

To fix this, create a new connection when send requests
fail because of network unreachability.

This change is darwin-only, although extended it to other platforms
should be straightforward.
