Subject: [PATCH] nixos/zigbee2mqtt: add RestartSec

After a cold reboot, zigbee2mqtt didn't properly come up.
The logs showed it crashed too often too quickly, and then systemd
stopped trying to restart it due to rate-limiting.

It might be due to the network not being up yet, or the Zigbee
coordinator still booting.

Either way, with a RestartSec=10, it did come up.
