winex11: Bias MapVirtualKeyEx(MAPVK_VSC_TO_VK) against numpad vkeys.

Browse Source 
The scan codes for the numeric keypad keys and those for the arrow keys and
keys like Home, End, etc. often match (ignoring the extended key bit).
However, if you map from one of those scan codes to a vkey, Windows reliably
prefers the non-numpad vkey.
