Split out ebtables anti-leak rules in phantap-early, improve logs

At START=01 "log" is not started yet so failsafe warning was not working.
Also uci defaults are applied at START=10 in "boot", so setup() was overidden on first boot.

The anti-leak rules do need to run really early, so move them to phantap-early,
and set START=90 in phantap.
