scripts/om-fwupgradecfg-gen.sh: Fix u-boot image md5sum check
The u-boot on Open Mesh devices checks the whole transfered image against a
md5sum. This is stored inside the option filemd5sum inside the
fwupgrade.cfg. The bootloader will not check it when this setting is
missing and could therefore write invalid images to the flash.
