Update version file paths to use VERSION.in (#1642)

**Link the Issue(s) this Pull Request is related to.**
#1637

**Summarize your change.**
- Updated version file paths in setup scripts to use VERSION.in (correct
file name in the Opencue project) instead of VERSION
- Fixes the error when running `sandbox/install-client-sources.sh`
- `sandbox/install-client-sources.sh` calls `pip install pycue/
pyoutline/ cueadmin/ cuesubmit/ cuegui/` and the `setup.py` in these
directories should use `VERSION.in` not `VERSION`
