Moved the crash monitors outside of the game executables

This is essentially https://github.com/OpenRA/OpenRA/pull/6759. I just adjusted https://github.com/Mailaender/OpenRA/commit/595ef07476ad7d865eb80419322a708eb9d4bb53 to not install files that are going to be removed sooner in the first place as I suggested. My hope is that it makes the twisted packaging scripts a little easier to understand.
