vbo: fix crash in vbo_exec_bind_arrays()
When a vertex shader uses generic vertex attribute 0, but not gl_Vertex, we need to set attribute[16] to point to attribute[0]. We were setting the attribute size, but not the pointer. Fixes crash in glsl/multitex.c when using the VertCoord attribute instead of gl_Vertex.
