lat9nq 2817ef1a53 externals: Don't set FOUND or VERSION on LIBUSB 
Fixes an issue where libusb.h wouldn't be found when building yuzu on
MSVC.

This only affects the "traditional" CMake pathway for linking libusb to
yuzu AKA MSVC. For autotools we still want to set these variables before
configuring SDL.
