Brad Fitzpatrick b8edb7a5e9 control/controlclient: add Debug field to NetworkMap
As part of disabling background STUN packets when idle, we want an
emergency override switch to turn it back on, in case it interacts
poorly in the wild. We'll send that via control, but we'll want to
plumb it down to magicsock via NetworkMap.

Updates tailscale/corp#320
