image_types.bbclass: implement jffs2 summary images (sum.jffs2)
* Building the jffs2 filesystem to include summary information speeds up
* the mount process considerably at the cost of increased size.
* The rate of speedup is generally higher on NAND chips and on the chips
* where the erase block size is large.
