iotests: Test downgrading an image using a small L2 slice size
expand_zero_clusters_in_l1() is used when downgrading qcow2 images
from v3 to v2 (compat=0.10). This is one of the functions that needed
more changes to support L2 slices, so this patch extends iotest 061 to
test downgrading a qcow2 image using a smaller slice size.
