[Piglit] [PATCH 06/11] 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.

v2: Add to all.tests.  Require GL version < 3.1 because the extension
became part of the core spec then.  Comments by Eric Anholt.
