[REQ] support for multi platform and cross platform builds and images

Improvement of existing experience

What is your request or suggestion?

While the container platform manifest is generated correctly, Dalec only produces binaries for packages/images that match the host OS. Dalec should support multi and cross platform binaries, at least for Go.
