support/scripts/genimage.sh: pass an empty rootpath to genimage

Browse Source 
genimage makes a full copy of the given rootpath to ${GENIMAGE_TMP}/root
so passing TARGET_DIR would be a waste of time and disk space. We don't
rely on genimage to build the rootfs image, just to insert a pre-built
one in the disk image.
