op-e2e: Wait for external clients to terminate after Kill()

Although ideally, all python minor versions (3.x) would be backwards
compatible, unfortunately that is not the case.  Consequently, sometimes
developers will have multiple python builds available on their systems,
not just a single `python3`.  This change simply makes the python binary
name a parameter of the Makefile so that affected developers may pass:

```
PYTHON=python-3.9 make
```

Or similar.
