Connect the Departures Lobby's Security post's vents, in Icebox (#5299)

## About The Pull Request
So turns out Icebox can still be voted upon.

And turns out it has a small mapping issue.

Don't worry, I fixed it. Concern yourself with other problems about
Icebox.
## Why It's Good For The Game

## Changelog

:cl:MichiRecRoom
fix: IceBox had a vent and scrubber not connected, within the security
post at the Departures Lobby. That's fixed now.
