wgengine/monitor: fix other potential crashes on Linux
...
Never return "nil, nil" anymore. The caller expected a usable
interface now. I missed some of these earlier.
Also, handle address deletion now.

wgengine/monitor: don't call LinkChange when interfaces look unchanged
...
Basically, don't trust the OS-level link monitor to only tell you

Also, move the interfaces package into the net directory now that we
have it.
