macosx: Constrain fscontroller hide-timeout

This constrains timeout to non-zeor.
Initializing the timer with 0 seconds will make it fire every
0.1 milliseconds instead, which is too freqeuntly. It caused the
fscontroller to flicker between animation states and never be fully
visible, which is addressed by forcing a value of at least 1 second.
