fix(prebuild): Fix prebuild double upload

[jhermsmeier]

Electron 1.8.x and 2.0.x have the same module ABI (v57),
causing the uploads to conflict and become reserved, yet not complete,
in turn causing further uploads and downloads to fail for that prebuild.

Change-Type: patch
See also: prebuild/prebuild#221

It took a really frustrating amount of searching to find (why is this not commonly published knowledge??) but I eventually found https://github.com/lgeiger/node-abi/blob/master/index.js#L51 which was the only "definitive reference" I could find. (Unless I was using entirely the wrong search-terms of course)

@lurch The modules versions <=> node version mapping is also documented on https://nodejs.org/en/download/releases/ – iirc it's tied to v8's breaking API changes, so it's a bit opaque. Another place you can also check it, is through process.versions;

$ node
> process.versions
{ http_parser: '2.8.0',
  node: '6.14.3',
  v8: '5.1.281.111',
  uv: '1.16.1',
  zlib: '1.2.11',
  ares: '1.10.1-DEV',
  icu: '58.2',
  modules: '48',
  napi: '3',
  openssl: '1.0.2o' }

Ah, so it is! Shame that it doesn't also cover Electron though (which my link did 😉 )

Yeah, I found that documented, but that obviously only tells you the module ABI of your currently-running version, not of all versions 🙂
