vio: Don't init ncurses in VioGetMode().

Info-Zip unzip.exe uses this but doesn't actually _need_ anything but
stdout, so don't mess up the terminal if we don't have to.

We might actually _need_ to query terminal characteristics at some point
in a complete implementation of VioGetMode, but for now this is fine.
