cli: always return correct version

[patrickhulce]

Summary
For some reason in our published bundle, version doesn't work. To repro...

docker run -it --user root --entrypoint /bin/bash node:14-buster
$ npm install -g lighthouse
$ lighthouse --version
unknown

Sadly this doesn't actually repro within our repo, so testing is rough, but manually applying this patch to an install in the docker container had the intended effect.
