Version control go tools

This MR adds the Go tools we depend on in the Makefile to go.mod so when we go get them they are the same. Otherwise, we would end up with cases where go install on the CI server would install a version different from the one a developer has locally, because he either go get-ed the binary or built it himself.

We are already doing this in the Runner:

• Makefile
• tools.go

This should fix Jobs where mockery formats imports differently
