[MIRROR] [NO GBP] Post-round blob zombies no longer offer themselves …

…to ghosts (#2799)

* [NO GBP] Post-round blob zombies no longer offer themselves to ghosts (#82542)

## About The Pull Request

This should properly fix the post-blob-win audio/notif spam for real
this time.

I wanted to preserve the effect as much as possible, so they just don't
poll for ghosts when the round is already over.
## Why It's Good For The Game

Closes #80998 for real this time.
## Changelog
:cl: Rhials
fix: The tide of post-round blob zombies when a blob wins will no longer
break the speakers in your headset.
