[CLOSED PR] Nerfs the departure time reduction on emagged shuttles

[Drewmajor11]

I'd also say this isn't really needed. Emagging shuttles can be annoying but doesn't have much of an effect on the actual round and traitors already have a pretty hard time hijacking. An emag would a lot of the time just prevent a wormhole throw rampage on the entire crew and reduce the casualties.
