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.

Allows to use the same unit for all definitions of the blocksize to be
consistent regardless of the used filesystem.

Now that the "sysupgrade-nand" step is used by non-NAND targets as well,
rename it to "sysupgrade-tar" to make it more generic.
