Exploitables no longer runtime on examine and don't expose antags. (#3362)

## About The Pull Request

Seems the logic here was reading variables from the person being
examined.. not the person examining.

Yes this meant that souless mobs would runtime, and anyone could meta an
antag because antags would show the option to view exploitables when
others would not.
## Why It's Good For The Game

Holy shit how did I miss this in a review
## Proof Of Testing
I tested it, no runtimes related to examination
