    expect: use u-a for mkpasswd
    
    * when busybox is built with CONFIG_CRYPTPW=y, then it will provide
      alternative for mkpasswd, which will fail in postinst, because
      mkpasswd from expect wasn't using u-a:
      update-alternatives: Error: not linking rootfs/usr/bin/mkpasswd to
      /bin/busybox.nosuid since rootfs/usr/bin/mkpasswd exists and is not
      a link
