SCI: Fixed the speed in the intro of PQ2, version 1.002.011 (bug #3102071)

Browse source 
In version 1.002.011, global 3, used for timing, is incorrectly initialized
to 0, whereas it should be 6 (like in other versions). Initializing it to
the correct value fixes the speed in the intro. This has been based on the
patch for that version by NewRisingSun(NRS) / Belzorash
