Until recently, qemu-img create displayed cluster_size=0 for the default cluster size. It is changed to display the real cluster size now, which results in the cluster size not being filtered out any more. If the cluster size is specified explicitly in CLUSTER_SIZE, keep the output, and if using the default, filter it out. This mostly restores the old behaviour of the test cases; test 015 must be fixed to use CLUSTER_SIZE instead of using extra_img_options for it.
