[Buildroot] [PATCH 7/9] board/raspberrypi/post-image.sh: pass an empty rootpath to genimage

From: Carlos Santos <unixmania at gmail.com>
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.
