[benchmark] Use python3 for subprocesses, too

After grpc#28963, the Python entry points run with "python3" found on the PATH. It makes sense to use the same for subprocesses, for two reasons: - There might be no "python" in the PATH, as in my Mac with brew - Having a different Python for subprocesses, especially if it's a Python 2, is asking for trouble.
