testing/tests/package/test_python: refactor TestPythonBase

Convert TestPythonBase to a true base class that only provides code
implementing various tests without defining tests themselves in a
"discoverable" form.

To retain correct testing functionality, add TestPython2 derived class
that uses code from TestPythonBase to define actual runnable test.
