Enable joystick events in background

Browse Source 
Capture the gamepads even when the window is not focused.

Note: In theory, with this flag set, we could capture gamepad events
even without a window (--no-window). In practice, scrcpy still requires
a window, because --no-window implies --no-control, and the input
manager is owned by the sc_screen instance, which does not exist if
there is no window. Supporting this use case would require a lot of
refactors.
