glx_arb_create_context_profile: Verify that the core profile is supported for OpenGL 3.2

NVIDIA's closed-source driver passes this test.  AMD's closed-source
driver has not been tested.  NVIDIA's closed-source driver supports
both core and compatibility profiles.

v2: Try to create a core profile both with and without the core
profile mask.  This was suggested by Chad Versace.
