[PATCH] D121423: [VFS] OverlayFileSystem should consistently use the last-added FS first

We had some discussions around the issue of needing to replace the returned path with the original, but that not being possible because of `use-external-names: true`. I'm going to put up a separate patch that should make it possible to detect when an external path was returned and then not replace in that case. We can then use that here.
