scripts/om-fwupgradecfg-gen.sh: Generate sha256sum for uboot verification
Future Open Mesh u-boot versions are changing the check of the image files (vmlinux, rootfs) from md5 to sha256. Having both in them should be enough to ensure backward and forward compatibility. Signed-off-by: Sven Eckelmann <sven.eckelmann@open-mesh.com> Backport of r49140
