Change /usr/bin/python -> /usr/bin/env python in tests (#23)

This was needed to get some of the tests passing when using venv (my system doesn't have python3 symlinked to /usr/bin/python, but venv will stick it on the PATH), and it seems to be what PEP 394 recommends: https://peps.python.org/pep-0394/#for-python-script-publishers
