Fixes hacked autolathes and limbgrowers (tgstation#72853)

## About The Pull Request

In my old PR I made a change to how hacked designs worked, however I
later changed it so the code would look cleaner, unaware that this
actually broke them.

This fixes both machines, allowing them to once again print things,
hacked or not.

## Why It's Good For The Game

Closes tgstation#72760
Closes tgstation#72806
Closes tgstation#72823

## Changelog
