[Buildroot] [git commit] testing/tests/package/test_python: do not hardcode interpreter name

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=ded5fa305985dff1585b1632697d2ee7297300b1
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

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