Use maintained fork of npm-run-all

Similar to emberjs#20522 it can be hard for users of `npm-run-all` to find out that there's a maintained fork: https://github.com/bcomnes/npm-run-all2

In my drive to raise awareness for `eslint-plugin-n` I'm therefore also making PR:s for `npm-run-all2` for projects that contain `npm-run-all`
