block: Improve empty format-specific info dump
When a block driver supports obtaining format-specific information, but that object only contains optional fields, it is possible that none of them are present, so that dump_qobject() (called by bdrv_image_info_specific_dump()) will not print anything. The callers of bdrv_image_info_specific_dump() put a header above this information ("Format specific information:\n"), which will look strange when there is nothing below. Modify bdrv_image_info_specific_dump() to print this header instead of its callers, and only if there is indeed something to be printed.
