This makes sense, because we're forcing this environment variable on Windows
right now, for the mouse acceleration thingey. So if SDL_Init() fails, and we
had forced this variable, we should unset and try again, in case we get lucky.

(this can happen when we force "directx" but the Windows installation is in an
advanced state of corruption. Windib will still work in this case, many times,
albeit with a sloppier mouse control.)

The function in question is Sys_GLimpInit() in sys_win32.c ...
