PATCH 1/1 image.bbclass: Only append to IMAGE_LINK_NAME if it was already set

create_symlinks does not create any links if IMAGE_LINK_NAME is empty. Unfortunately, setup_debugfs_variables unconditionally appends '-dbg' which results in a previously-empty IMAGE_LINK_NAME containing just '-dbg'. Let's check that it's not empty before appending.
