Andrew Dunham 727acf96a6 net/netcheck: use DERP frames as a signal for home region liveness
This uses the fact that we've received a frame from a given DERP region
within a certain time as a signal that the region is stil present (and
thus can still be a node's PreferredDERP / home region) even if we don't
get a STUN response from that region during a netcheck.

This should help avoid DERP flaps that occur due to losing STUN probes
while still having a valid and active TCP connection to the DERP server.

RELNOTE=Reduce home DERP flapping when there's still an active connection

Updates #8603
