Give maintenance drones the duffel bag instead of a new backpack (#2953)

* FREE MAINTDRONE STORAGE

Give maint drones their dufflebag instead of a meme'd in backpack that
can't store shit

* FIX TYPES

I'm dumb

* Add extra items to the drone duffelbag

Forgot the t-ray scanner, gas analyzer and pipe dispenser from the
starting bag. Also nixxes a leftover initialize proc for the bag.
