[Piglit] [PATCH] arb_texture_buffer_object: Verify some behavior when the extenion isn't supported

[Ian Romanick]

From: Ian Romanick <ian.d.romanick at intel.com>

If the extension is not supported, applications should not be able to
bind to the texture target or the buffer object target.

This currently fails on Mesa, and I'm working on a fix.  It's
currently tangled in some other work, but a patch will go out in the
next day or so.
