[PATCH 2/2] wined3d: Limit GLSL version to 1.30 when OpenGL 3 is not supported.

Virtualbox's OpenGL passthrough apparently advertises GLSL 4.50 on a
GL 2.1 driver. We can't really take advantage of newer GLSL without
the corresponding OpenGL support so just limit the GLSL version and
avoid further trouble.
