Run Python scripts under the chosen version

Browse Source 
The Python scripts have unversioned Python shebangs so tests will
fail if the chosen Python version is not unversioned Python.

Copy the scripts to tmp dirs and change the shebang to the chosen Python.

Also prevent sharness from adding the unversioned Python scripts to PATH.
