In update_virtual_gamepad_display() which is called every tick, do not actually call the functions to
hide and show the virtual gamepad unless the state has changed, since calling them every tick
causes arrow key presses to be mangled (it is necesary to clear arrow key presses whenever the
virtual gamepad is hidden/shown to work around an older stuck-key bug)

This change fixes half of bug #2015 "Arrow keys broken for gamepads on Android port"
(and has been tested to confirm that it does not reintroduce other gamepad bugs)
