Change the dispatch offsets for the VertexAttrib*NV functions so they don't
alias with the corresponding ARB functions.
GL_ARB_vertex_shader (and OpenGL 2.0's) VertexAttrib functions don't alias
with conventional vertex attributes, as GL_NV_vertex_program does.
So, the ARB and NV version of VertexAttrib need to be distinct.
