The CCK will be able to be updated by an ultravisor call. For security reasons, this feature must be enabled at Secure Execution header creation time. Because this makes it possible to dump without having set a CCK earlier, the requirement to specify a CCK when creating an image with guest dump support is extended to also allow for CCK update instead. Change a CLI test for this that was a duplicate anyway.
