[PATCH v3] Convert Python scripts to Python 3

[Alistair Francis <alistair dot francis at wdc dot com>]

Change all of the #! lines in Python scripts that are called from
Makefiles to reference /usr/bin/python3.

All of the scripts called from Makefiles are already run with Python 3,
so let's make sure they are explicitly using Python 3 if called
manually.
