win-capture/graphics-hook: Fix wrong HWND

Browse Source 
Game capture assumes the top-level ancestor HWND, not a child HWND.
This fixes bugs such as the VLC window not capturing anymore due to the
fact that the capture HWND of VLC is a child window of the main VLC
window and not the main VLC window itself.
