revive-runner: install with locked dependencies (#286)

Make the installation of  `revive-runner` easier:
- Use locked dependencies to avoid issues with downstream crates
- Make the llvm-context crate an optional dependency to the runner
- Add it to the default `test` target ensuring that this actually works
