Build multiarch (amd64 and arm64) images

Makes changes to the scripts in build/tools to build and push multiarch
images. Now runs two `docker build` commands to build images for
individual architectures, and an additional `docker manifest create` to
create the multiarch manifest. When pushing `docker manifest push` is
used instead of `docker push`.
