gdkglcontext-win32-wgl.c: Always request alpha bits

...when we are using wglChoosePixelFormatARHB().  This ensures that we
hvae a HDC with a pixel format that will really support alpha bits, as
we did for the traditional ChoosePixelFormat().

Thanks to Patrick Zacharias for testing and pointing things out.
