Update events polyfill for node 10

[SamBroner]

Based on this issue #8

I noticed that I have 3 additional files created during build. In this repository do you expect those to be checked in?

Possibly @manucorporat

Just because I noticed @manucorporat hasn't been active on the other open PRs, possibly @mlynch or @dwieeb? No rush! Happy holidays.

Hoping this gets merged soon cause I'm having the same issue:

(!) Missing shims for Node.js built-ins
Creating a browser bundle that depends on 'events'. You might need to include https://github.com/ionic-team/rollup-plugin-node-polyfills

@FredKSchott, may be relevant for @snowpackjs?

@SamBroner we're going to go ahead and fork this repo, with plans to eventually bring under the official Rollup org. See rollup/plugins#51 (comment)

Would love if you could create this PR onto our repo: https://github.com/snowpackjs/rollup-plugin-node-polyfills
