SCI32: Block RAMA from creating PREF.DAT file

This file normally stores brightness, music volume, and most
recently used save game directory. Since we store the music volume
ourselves and don't use the save game directory, the only
potentially useful information is the brightness level, and that
is fine to just restore from the save games.
