[Buildroot] [PATCH v2 4/6] testing/tests/package/test_python: do not hardcode interpreter name

[Andrey Smirnov]

In order to be able to leverage the same test code for testing
different python interpreters (or wrappers around CPython) allow
classes derivate of TestPythonBase to override the name of the
executable used to run tests.
