moby: disable gpsd

1. i wasn't actually relying on it for anything. 2. it's 100k LoC which runs as root (?), in a totally un-secured systemd service.

i may be enabling something similar like this in the future, to prevent geoclue from deciding to disable the GPS. i'll probably be going with the simpler gps-share or gnss-share for that
