Use a go build cache to speed up builds. 

With a docker build cache already primed with the build image I am seeing
`time make build -f docker.Makefile DOCKER_BUILDKIT=1 GO_BUILD_CACHE=n` takes
more than 1 minute.

By contrast `time make build -f docker.Makefile DOCKER_BUILDKIT=1
GO_BUILD_CACHE=y` takes less than 10s with a hot cache irrespective of whether
the source tree has changed
