Disconnect real Wiimotes when disconnected by games

This commit makes real Wiimotes really disconnect when they are
disconnected by the emulated software, which is more similar to how
it works with a real Wii and allows Wiimotes to be disconnected after
timeout for power saving.

This is currently only enabled on Linux, because of limitations on
the other platforms.
