Enhancement (ci): Create artifact with base and layered size at end o…

…f `build.sh` and test `update` size (startersclan#114) As discussed in startersclan#113, there needs a test to ensure the image doesn't grow significantly during `update`. This PR creates an artifact with `BASE_SIZE`, `LAYERED_SIZE`, and `DIFF`, which can be used in later steps such as with `notify.sh`.
