    yocto: slides: update description of rootfs generation
    
    The rootfs_deb_do_rootfs code does not exist in oe-core since a long
    time. Remove it and replace it with a more descriptive line in the previous
    slide.
    
    Also add the first step for rootfs generation: creating an empty directory.
