glx: Fix returned values of GLX_RENDERER_PREFERRED_PROFILE_MESA


If the renderer supports the core profile the query returned incorrectly
0x8 as value, because it was using (1U << __DRI_API_OPENGL_CORE) for the
returned value.

The same happened with the compatibility profile. It returned 0x1
(1U << __DRI_API_OPENGL) instead of 0x2.

Internal DRI defines:
   dri_interface.h: #define __DRI_API_OPENGL       0
   dri_interface.h: #define __DRI_API_OPENGL_CORE  3

Those two bits are supposed for internal usage only and should be
translated to GLX_CONTEXT_CORE_PROFILE_BIT_ARB (0x1) for a preferred
core context profile and GLX_CONTEXT_COMPATIBILITY_PROFILE_BIT_ARB (0x2)
for a preferred compatibility context profile.

This patch implements the above translation in the glx module.

v2: Fix the incorrect behavior in the glx module
