mesa/main: set PREFER_DP4 to match position_invarient code
This is a quick fix for z fighting in quake4 caused by the mismatch between vertex transformation here and in the position_invarient code. Full fix would be to make this driver-tunable and adjust both position_invarient and ffvertex_prog.c code to respect driver preferences.
