Remove fallbacks for missing round(), copysign() and hypot() in Python/pymath.c. Python now requires these functions to build. These fallbacks were needed on Visual Studio 2012 and older. They are no longer needed since Visual Stuido 2013. Python is now built with Visual Studio 2017 or newer since Python 3.6.
