[PATCH 08/10] tests/qemu-iotests: Explicit usage of Python 3

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

Use the program search path to find the Python 3 interpreter.

Patch created mechanically by running:

  $ sed -i "s,^#\!/usr/bin/\(env\ \)\?python$,#\!/usr/bin/env python3," \
      $(git grep -lF '#!/usr/bin/env python' | xargs grep -L 'if __name__.*__main__')
