wineps.drv: Add missing #include <stdarg.h> in support of #include "windef.h". "windef.h".

    wineps.drv: Use SetRect/SetRectEmpty instead of open coding them.
 
broke the build on FreeBSD 10 and probably other platforms that are
less aggressive about providing/including other headers than glibc.

Luckily the fix is straightfoward... :-)
