Revert "Install (platform-independent) python scripts to the PYTHONDIR rather than PYTHONARCHDIR."

This reverts commit de4b8943bfb40e2f50c9e4e2ee5d39e986317d08.

PYTHONDIR and PYTHONARCHDIR are both incorrect - they're the
distribution's python locations, rather than the python locations for
third party applications. For the moment, using PYTHONARCHDIR seems
better though, because it works around an issue on Fedora/RedHat.
