Store our image size (known at build time) in our version struct (now renamed to image_data). This will allow us to more efficiently determine the size of an image in a follow-up CL. Note that compatibility is broken for old ROs that do not include this CL. BUG=chromium:577915 TEST=Verify on kevin + lars + lars_pd that stored image size matches output of system_get_image_used() for both RO and RW images.
