wbemprox: Report 4095MiB video memory if it overflows.

That's what Windows do apparently. Anything with more than 4GiB of VRAM
would report less otherwise, confusing the VRAM detection in some games.

The Mafia III launcher is trying to open a warning popup with a 8GiB
VRAM GPU for instance, as the reported value overflows to 0.
