i915: fallback for cube map texture.
The i915 (and related graphics cores) only support TEXCOORDMODE_CLAMP and
TEXCOORDMODE_CUBE when using cube map texture coordinates, so fall back to
software rendering for other modes to avoid potential gpu hang issue. This
fixes scorched3d issue on 945GM(see bug 14539).
