[MERGED PR] Removes medical locker access from security officers on RP

[DisturbHerb]

Personally rather opposed to this change in its current form. This change would do very little to solve the problem at hand, as medical lockers don't usually contain the medical supplies Security Officers keep stealing. At best, this would just stop Sec from buying medical supplies from Cargo.

The way I'm reading this, this change would also prevent Security from placing the belongings of dead personnel in the lockers in Cloning, though I don't really like the idea of Security using the cloner anyway.
