[issue39246] shutil.rmtree is inefficient because of using os.scandir instead of os.walk

[Felipe A. Hernandez]

New submission from Felipe A. Hernandez <ergoithz at gmail.com>:

os.rmtree has fd-based symlink replacement protection when iterating with scandir (after bpo-28564).

This logic could be greatly simplified simply by os.fwalk in supported platforms, which already implements a similar (maybe safer) protection.
