Abductors have an antag sound stinger upon being rolled (#84180)

## About The Pull Request

This adds an antag stinger for being selected as an abductor
scientist/agent.

Some nice extraterrestrial whooping with a classic theremin stinger in
the background. It's a bit on the longer side but that's only because
the second whoop takes a while to peter out.

Both attributions handled in attributions.txt, both were CC0.
## Why It's Good For The Game

The theremin is peak greylian representation. Helpful for getting into
the mindset of a spooky ayylien.

I think more antags should have these audio stingers. They invoke a
Pavlovian response equal in power to the almighty bwoink.
