Re: [PATCH 2/2] qemu-img: Require -F with -b backing image

Back in commit d9f059aa6c (qemu-img: Deprecate use of -b without -F), we deprecated the ability to create a file with a backing image that requires qemu to perform format probing. Qemu can still probe older files for backwards compatibility, but it is time to finish off the ability to create such images, due to the potential security risk they present. Update a couple of iotests affected by the change.
