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.

metrics: add a LabelMap type for variables with 1 label dimension.
...
This lets us publish sets of vars that are breakdowns along one
dimension in a format that Prometheus and Grafana natively know
how to do useful things with.
