Use correct extensions in wxDynamicLibrary::CanonicalizeName() on OS X.

Contrary to the documentation, this function incorrectly appended the
.bundle extension on OS X for libraries as well as modules.

Fixed to use .dylib for libraries (wxDL_LIBRARY) and continue to use
.bundle for loadable modules (wxDL_MODULE). Change GetDllExt() to take optional wxDynamicLibearyCategory argument.
