This commit updates the used Go version to 1.16. The biggest benefit from this is that with Go 1.16 (and the latest Goreleaser) support for Apple Silicon is available, therefore wtf would work on Apple Silicon.

- Use progressive build to reduce final image size
- Download source during build so only Dockerfile is required to be present on the build host
- Add a `version` arg so any tag or branch can be built: `docker build --build-arg=version=v0.25.0 -t wtf .`
