Remove deprecated opengl stuff from opensubdiv

This removes glGetBooleanv queries for GL_LIGHTING. This has been #ifdef'd
out with legacy opengl disabled. Thus a false positive still shows up in
the gl queries. Also, note that this removes support for wireframes in
opensubdiv, when desabling legacy opengl, which should be fixed later.
