Only apply --image-opts to the topmost image when listing an entire
backing chain. It is incorrect to treat backing filenames as image
options. Assuming we have the backing chain t.IMGFMT.base <-
t.IMGFMT.mid <- t.IMGFMT, qemu-img info fails as follows:
$ qemu-img info --backing-chain --image-opts \
driver=qcow2,file.driver=file,file.filename=t.IMGFMT
qemu-img: Could not open 'TEST_DIR/t.IMGFMT.mid': Cannot find device=TEST_DIR/t.IMGFMT.mid nor node_name=TEST_DIR/t.IMGFMT.mid
