wscript and cscript always crash in CommandLineToArgvW

These apps are marked as console apps so wWinMain's lpCmdLine parameter is set to NULL by our CRT startup code.
In Wine, both of these are marked as GUI apps (although Wine's startup code doesn't have this issue anyway).
On Windows, cscript is CUI, wscript is GUI as expected. We should use this approach, since unlike in Wine, making cscript GUI is gonna be problematic for us since it'll be missing the console.
