Windows: packaging MIcrosoft redistributable

[MatthieuDartiailh]

Currently kiwi does not package the Microsoft redistributable package with its wheel which can cause some corner case issues. Scipy package it with the wheel (cf https://github.com/MacPython/scipy-wheels/blob/master/appveyor.yml) and we should perhaps do the same.

@matthew-brett @cgohlke I would like your input on this since this also affects https://github.com/MacPython/atom-wheels and https://github.com/MacPython/enaml-wheels
