Tweak dh overrides to ensure that dump1090-fa is restarted on upgrade.

We retain --no-restart-after-upgrade so that dump1090 is stopped
in prerm and restarted in postinst, not because dump1090 will be
confused by running during an upgrade, but because on low-resource
machines like a Pi Zero, dump1090's CPU use can significantly slow
down the upgrade process.
