Philippe Mathieu-Daudé 903cb1bf39 tests/qemu-iotests: Explicit usage of Python 3 (scripts with __main__)
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 -l 'if __name__.*__main__')
