This reverts commit 4fdd60558a7e9cad217c7689de377e74aa0a8f31.

Testing manually in: https://drone.platform.teleport.sh/gravitational/teleport/34120

The relevant builds are all green,

The failure appears to be one of those random network errors that osx runners tend towards, so I consider this manually confirmed and ready for merge 👍

Why is this being reverted? I know about the PROTOC_VER breakage (just hit it), but what was wrong with the other stuff? It really helps me to review if I understand why something is being done, not just what is being done.
