The shebang for a python script should be "/usr/bin/env python" and not
"/usr/bin/python". On some OSes like AIX, python default path is not under
"/usr/bin" ("/opt/freeware/bin" for AIX).
Note the main reason behind this change is that AIX rpm will add a
dependency on "/usr/bin/python" instead of "/usr/bin/env".
