vbo: disable the GL_ARB_draw_elements_base_vertex rebase path
This was introduced with commit 92d7ed8a20d4a018ce5324e6537ae7b478b9e5bf. It causes rendering of stray polygons (with sw rendering at least) when running the OGL Distilled / Picking demo (click on an object). This needs additional debugging to fix/restore. Found one suspect thing: in _tnl_draw_prims() there's some mixed signed/ unsigned arithmetic/comparing at line 422 that may be incorrect.
