sbcl.pkgs: use Quicklisp versions of tar and tar-file
Out-of-quicklisp version that was manually specified in packages.nix stopped building after Quicklisp dist bump, because of a change in one of its dependencies. Switching to using the one imported straight from Quicklisp, in imported.nix. See https://github.com/NixOS/nixpkgs/pull/238790#issuecomment-1622040328
