[PATCH v2 1/3] qemu: domain: Convert detected 'iso' image format into 'raw'

While our code can detect ISO as a separate format, qemu does not use it as such and just passes it through as raw. Add conversion for detected parts of the backing chain so that the validation code does not reject it right away.
