Docker improvements

- Modify onionr.sh to parse env and supply args to run-onionr-node.py
- Run onionr by default rather than bash
- Run as unprivileged user by default instead of root
- Use /app for all code
- Specify python 3.7 (3.8 fails to build cffi)
- Use apt-get rather than apt (apt's CLI is not stable)
- Slight reformatting and consolidation
