Fix installing Python modules on systems that use /usr/lib for Python while installing other libraries in /usr/lib64. Rewrite CMake logic to query correct directories from Python, similarly to how prepare_binding_Python.py does it. Furthermore, change the regex used in get_relative_lib_dir.py to allow 'lib' without suffix. I think that the code can be further improved but I'd like to take this enterprise in smaller steps in case one of them breaks something.
