Gives maint drones random designations (#78573)

## About The Pull Request
Right now, drone ghost spawners give all drones the name "drone." This
makes it difficult to differentiate drones, both as a drone in drone
chat and as a non-drone. This gives all drones a unique identifier like
posibrains.

Also changes a couple of 1s to TRUEs

## Why It's Good For The Game
It's good to be able to identify drones, and for drones to be able to
identify each other.

## Changelog
🆑 Tattle
qol: drones now have individual names, instead of just "drone"
