Support a new CLANG_LIBRARY_PATH environment variable for the Python binding tests. This variable can be used to force the bindings to load libclang.* from a specific directory. I plan to use this when integrating Python binding tests with the CMake build system. Currently, those tests load libclang.so from default search paths, so I would have to rely on platform-specific mechanics such as LD_LIBRARY_PATH. Instead of copying the whole logic necessary to handle platform differences into yet another place, it's easier to just add a dedicated variable for this purpose.
