While looking for some low hanging chores to do, I stumbled upon `.travis.yml`. Thought we might as well tell Travis to cache the npm dependencies to speed up our builds. Knowing we've got the entire dependency tree locked down with `package-lock.json`, it can't hurt to cache them, right? Refs https://docs.travis-ci.com/user/caching/#npm-cache /cc @nodejs/github-bot
