Brad Fitzpatrick ffa70a617d wgengine{,/monitor}: restore Engine.LinkChange, add Mon.InjectEvent
The Engine.LinkChange method was recently removed in
e3df29d488 while misremembering how
Android's link state mechanism worked.

Rather than do some last minute rearchitecting of link state on
Android before Tailscale 1.6, restore the old Engine.LinkChange hook
for now so the Android client doesn't need any changes. But change how
it's implemented to instead inject an event into the link monitor.

Fixes #1427

Brad Fitzpatrick 24fa616e73 wgengine/monitor: make Darwin monitor shut down cleanly, add test
Don't use os.NewFile or (*os.File).Close on the AF_ROUTE socket. It
apparently does weird things to the fd and at least doesn't seem to
close it. Just use the unix package.

The test doesn't actually fail reliably before the fix, though. It
was an attempt. But this fixes the integration tests.
