mesa: let GL3 buf obj queries not depend on opengl major version
While the ARB_map_buffer_range extension spec says nothing about these queries -- they were added in GL 3.0 --, it seems like this could be an error in the extension spec. This is one of the extensions, like ARB_framebuffer_object, that "back ports" OpenGL 3.0 functionality to previous versions. These extensions are supposed to provide identical functionality to OpenGL 3.0. The other cases of mismatches have been determined to be bugs in the extension specs. And tools like apitrace rely on such queries to function properly.
