Try go get codecov to ignore generated files

I have been struggling to validate this by:
* Using a codecov.yml file in my local checkout (it seems like this gets ignored, although the bash upload script does recognize it exists)
* Using the team yml configuration in codecov

No matter what I do, nothing seems to change about the code coverage. I'm wondering if this config actually has to be in the repo to do anything (as per https://docs.codecov.io/docs/caveats)
