Fix T37663: Black matcap when object located on a curve

Summary:
Issue was caused by GLSL samplers not valid anymore after
dupliobject was drawn into OpenGL displist.

Solution for now is to not use displist for active object
when matcap is used.

The same issue exists for regular GLSL viewport draw, and
this was solved by disabling diplist if draw_glsl_material
returns truth for current dupliobject.
