If we're a single-user installation of Nix, then we won't have root superpowers to just ignore the permission bits. This means that we'll need permission on the directory (if it's a directory) that we're moving in order to move it with rename, because it must update the ".." directory entry. Fixes NixOS#4295. This is already working in master, thanks to e913a29 (and followup cleanups).
