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. Signed-off-by: Sven Eckelmann <sven@open-mesh.com> SVN-Revision: 46925
