system: Use stored size in image_data for determining image_used
Image used size is now part of the image_data struct present in all
images at a fixed offset, so use it rather than scanning from the end of
the image.
BUG=chromium:577915
TEST=Verify on kevin + lars + lars_pd that system_get_image_used() returns
the same value as the old implementation, for both RO and RW images.
BRANCH=None
