Use VersionHelpers.h to simplify SystemUtil

A set of useful utilify functions called "Version Helper functions" has been available since Windows SDK 8.1.
https://msdn.microsoft.com/en-us/library/windows/desktop/dn424972.aspx

We can rely on them in SystemUtil instead of reimplementing the same logic.

This is just a code clean-up.  No behavior change is intended.
