powervr2.cpp: make opaque polygons opaque

Previously, MAME's pvr2 implementation treated all polygons as transparent.

This resolves missing graphics in certain games which were rendering opaque
polygons with alpha values which would make them transparent if they weren't
on the opaque list.

In the future, Punch-through polygons will also require special consideration.
These are polygons which support transparency but not blending (every pixel is
either entirely transparent or entirely opaque).  For now, they're still treated
the same as transparent polygons.
