gfx_fb: fix some broken keys only on Windows by calling winapi GetKeyState

Actually the whole numpad is busted in fbgfx but I couldn't be bothered fixing
them all.  I only fixed numlock, numpad5, printscreen, and scrolllock, and a
partial fix for pause (it misses most keypresses).

All these keys are still broken on other OSes.
