Forget close handle in get_file_info function.

Hi, thanks for your great work, and it seams that you forget to close handle in get_file_info function at jaraco/windows/filesystem/init.py line:254 (it should be a line 'handle_nonzero_success(api.CloseHandle(handle))' there?).

Thanks for the report. I've released the suggested change as 3.9.2.
