[yocto] [PATCH 2/2] sato: Remove questioned ISO image

[Yang Shi]

[YOCTO #1487]

For the liveCD image, interactive bootup is needed, but psplash prevents from
booting interactively. In such case ISO image is not usable, so remove ISO image
and the corresponding link and throw error info to warn outside to enable
unionfs in kenrel.
