Andrey Drobyshev b7867c8262 qemu-iotests: 024: add rebasing test case for overlay_size > backing_size
Before previous commit, rebase was getting infitely stuck in case of
rebasing within the same backing chain and when overlay_size > backing_size.
Let's add this case to the rebasing test 024 to make sure it doesn't
break again.
