There was a race in venv re-population due to a non-atomic `rm`, create sequence. There was no real need for the `rm` and the create is atomic on its own; so just remove the `rm` which was only attempting to guard "corrupted" venvs in a slapdash way. Now the venv either exists or it doesn't from the script point of view. If the venv exists but has been tampered with, its execution will consistently fail until there is a manual intervention removing the venv dir offline. Fixes pantsbuild#14618 Fixes pantsbuild#16778 (cherry picked from commit cace851)
