This PR --> #1670 removes support for obsolete io.js versions, this is perfectly valid however because of the way that logic was originally implemented, over on the Electron team for our 1.x/2.x/3.x releases, we had to publish our headers with the iojs prefix instead of the node prefix.

As of node-gyp@5.0 these versions no longer work and currently we still support Electron 3 so ideally this would be fixed. I've raised a simple "revent the PR that broke it" PR, if that's acceptable it would be great to merge and release that, otherwise I can craft a PR to specifically introduce support back for these headers.
