One-Way Materials Market (#5137)

## About The Pull Request

Re-enables purchase of the GMM, however the GMM can only be used to
purchase materials not sell them.

## Why It's Good For The Game

Let the station buy materials if they're desperate/lowpop. If people
were selling insane amounts of material inflating the budget, just
remove the ability to sell. Don't remove the entire machine.

## Changelog

🆑 LT3
add: Galactic materials market can be used by cargo for purchasing
materials only
