This makes it easier to add more options to the backend without having to change
the signature.
While we're changing the signature, also adding a context.Context, which is not
currently used, but probably should be at some point.

- Rename image summary constructor
- Rename `newImage` into `newImageSummary`, since the returned type is
`*types.ImageSummary`
- Rename variables for clarity
- Rename `newImage` into `summary`, since the variable type is
`*types.ImageSummary`
- Rename `imagesMap` into `summaryMap`, since the value type
contained is `*types.ImageSummary`
- Only compute `DiffSize` when more than 1 reference to the layer
exists, since it is not used otherwise
- Move variable declarations closer to where they are used

This enables image lookup when creating a container to fail when the
reference exists but it is for the wrong platform. This prevents trying
to run an image for the wrong platform, as can be the case with, for
example binfmt_misc+qemu.
