Use DIB_PYTHON_EXEC to run commands

Browse source 
DIB_PYTHON_EXEC was added in I5fab0e192c3a2dad8f60e821c184479e24e33bcd
to export the python that disk-image-create is running under.  If dib
is installed with python3 then just calls "python" (python2) to run
sub-scripts, it fails to find itself.

This has been tested in devstack gates that use py3x
