Is your feature request related to a problem? Please describe.
cmd/loki/Dockerfile currently fails to build due to the absence of goyacc in the golang image it is based on.
Example: https://drone.grafana.net/grafana/loki/8355/3/3

To fix this, grafana/loki-build-image should be used instead. It is based on the same golang docker image, but has the tools required by the Makefile included. It is already used in cmd/loki/Dockerfile.debug.

Unfortunately, even though a grafana/loki-build-image based container is able to invoke goyacc from make, it cannot build arm based images.
Example: https://drone.grafana.net/grafana/loki/8426/4/3

Describe the solution you'd like
CI based arm and arm64 support for the loki-build-image container.

Describe alternatives you've considered
As a temporary measure, I am creating a PR that introduces the go tools required to build loki into cmd/loki/Dockerfile.
This duplication is likely to cause drift if left in place too long, but will unblock me until grafana/loki-build-image can be ported to arm and arm64.
