[PATCH v7 1/4] perf python: Prefer python3

[Ian Rogers]

From: Ian Rogers <rogers.email@xxxxxxxxx>

The PYTHON_AUTO code orders the preference for the PYTHON command to
be python3, python and then python2. python3 makes a more logical
preference as python2 is no longer supported:
https://www.python.org/doc/sunset-python-2/

Reorder the priority of the PYTHON command to be python2, python and
then python3.
