`make-disk-image` is a tool for creating VM images. It takes an argument `contents` that allows one to specify files and directories that should be copied into the VM image. However, directories end up not at the specified target, but instead at a subdirectory of the target, with a nix-store-like path, e.g. `/target/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx-source`. See issue https://github.com/NixOS/nixpkgs/issues/226203 . This change adds a test for make-disk-image's contents directory handling and adds a fix (appending `/` to rsync input directory names). This closes issue https://github.com/NixOS/nixpkgs/issues/226203 .
