image: pass device blocksize to padjffs2
At the moment the padding steps are hardcoded. Especially images for devices with a 4K sector size can be unnecessarily bloated using the hardcoded padding steps. It has been observed that 192Kb of padding was added to the image of a 4MB device, albeit due to the 4K sector size the minimum required extra padding for the jffs2 rootfs_data is 20Kb. In worst case it means that the image-size check could fail albeit there is enough space for all selected packages For device build code not exposing the blocksize, use the hardcoded padding further on.
