setup: preserve version part after the "+" on Windows...

setup: preserve version part after the "+" on Windows Code introduced in early 2010 (fb203201ce30) was dropping that part after "+". The rational is to preserve version on the format w.x.y.z where each part is a number. However we have not been using that format for a while (e.g. the rc suffix) and nobody reported any fire. So I am assuming that this code serve no purpose and I am dropping it. We can reintroduce a newer version of it (that would actually achieve its purpose) in the future if needed.
