gdi32/tests: Fix the SetDeviceGammaRamp() tests on Windows 10 1909.

SetDeviceGammaRamp() checks the specified ramp to prevent applications from setting malicious gamma ramps (e.g. hiding text by remapping its color to match the background). But Windows 10 1909 has fewer checks than later Windows 10 versions. Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=54593
