The tarball/disko-image build previews were hardcoded strings that never
included ${NIX_OPTS[@]}, so --dry-run always showed the same "would build"
command whether nix-cache's substituter/remote-builder got disabled by
nix_extra_opts's reachability probe or not -- the actual (non-dry-run)
build commands already applied it correctly, only the preview lied.
