Fixes #4210 (comment)
With containerd worker + non-overlayfs-snapshotter configuration, we've been using containerd's differ via containerd client but the compression level can't be applied in this configuration. This commit fixes this issue by compressing gzip with customized compression level on BuildKit't differ instead of containerd's differ. Uncompressed blobs and gzip blobs without customized compression level are still handled by containerd's differ.
