Go code is really fast to compile so we do not really need to use the cache features of `docker build`. So make a compile container instead. This can also output a build context and Dockerfile if you want to do a build. For reference, an uncached `docker build` of our Go code takes about 7s, a cached one 1.2s, and this takes 1.7s, so the best case is a little worse, but we save a lot of images, and the worst case is better. This is mainly designed to make the nested builds for containerd containers simpler too. Will add a variant for the C code as well. Also add `-static` to the flags so we always make static executables, which was omitted previously. Signed-off-by: Justin Cormack <justin.cormack@docker.com>
