Daniël de Kok d7f3186b48 dockerTools.buildLayeredImage: restore layer sharing
PR #58431 added /nix/store to each layer.tar. However, the timestamp was
not explicitly set while adding /nix and /nix/store to the archive. This
resulted in different SHA256 hashes of layer.tar between image builds.

This change sets time and owner when tar'ing /nix/store.
