Gives Janitor ERT no slips (#85607)

## About The Pull Request

Gives janitor ERT no slips instead of a clamp

## Why It's Good For The Game

Quite silly for the top of the top janitors from NT losing in a slip
battle with the regular station janny. I'm pretty sure no slip modules
weren't a thing when the ERT modsuits were made
