guf-image: Add minimal and small images

For faster testing and building smaller images are useful.
The guf-image is even now quite big (with ~160MiB).

So introduce guf-image-small and guf-image-minimal.
The former has debugging and package-management capabilities.
The latter is stripped down to basic features network access only.
