[PATCH v3 5/4] iotests: Enhance 223 to cover qemu-img map improvements

[Eric Blake]

Since qemu-img map + x-dirty-bitmap remains the easiest way to read
persistent bitmaps at the moment, it makes a reasonable place to add
coverage to ensure we do not regress on the just-added parameters to
qemu-img map.

My enthusiasm got the better of me - I whipped out this patch instead
of waiting for Eyal's response ;)
