rust-status: don't trigger dirstate v1 rewrite when only v2 data is changed The assumption that we need to rewrite (or append to) the dirstate if the ignore pattern hash has changed or if any cached directory mtimes have changed is only valid when using dirstate-v2. In dirstate-v1, neither of these things are written to disk.
