ubinize: add sequence number support
UBI now supports the image sequence number feature which prevents UBI from mistakingly accepting half-written images, if the image was written on top of an older image. Support this feature in ubinize and make it pick a random number for the UBI image sequence number. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
