Removes bitrunning unit tests (#78607)

## About The Pull Request
Removes the fraction of unit tests I thought would be safe.
Not thrilled that I have to exclude ALL unit tests now, but hey.

The issue is that atmos attempts to process on a turf which hasn't
initialized yet.
## Why It's Good For The Game
Other PRs can pass checks now
