[Piglit] [PATCH 3/5] glx_arb_create_context_profile: Verify that the profile is ignored pre-3.2

[Ian Romanick]

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

The profile mechanism is only meaningful for OpenGL 3.2 or later.
Verify that the profile setting is silently ignored when a version
earlier than 3.2 is requested.

NVIDIA's closed-source driver passes this test.  AMD's closed-source
driver has not been tested.
