Merge PR cosmos#1687: tools: Ensure Gopkg.lock is correct in linting

* tools: Ensure Gopkg.lock is correct in linting

This adds dep status to the lint process. Also fixes linting errors
that existed earlier. (not sure why they didn't show up on CI)

Closes cosmos#1574

* Update dep, use the lock file new dep version creates
