makefile: give better error for tool installed by wrong package (#13797)

I had protoc-gen-go installed through `google.golang.org/protobuf` instead of
`github.com/golang/protobuf` and `make proto` was failing silently.
This change will ensure you get an error:

```
protoc-gen-go is already installed by module "google.golang.org/protobuf" but
should be installed by module "github.com/golang/protobuf".
Delete it and re-run to re-install.
```
