ubi-utils: ubinize: add support for skipping CRC check of a static volume when opening
Let's let the user configure static UBI volume with CRC checking at opening disabled if desired. Introduce the skip-check setting for vol_flags configuration of a volume. There is no point in having both autoresize and skip-check set as skip-check is reserved for static volumes only and it's useless to have a static volume's size set to autoresize.
