zigbee2mqtt: use extra_hosts host-gateway instead of network_mode: host

Browse source 
docker-compose v1 cannot clear the ports list from the base compose with
ports: [] in an override, so network_mode: host caused InvalidArgument.

Use extra_hosts with host-gateway instead: maps 'mosquitto' hostname to the
Docker bridge gateway IP so mqtt://mosquitto:1883 reaches the host-networked
mosquitto process from within the bridge-networked z2m container.
Requires Docker 20.10+ (present on chelsty-infra).
