[waffle] [PATCH] glx: provide our own GLX_ARB_create_context_profile defines

[Emil Velikov]

As of recently the official Nvidia driver does provide its own GL
headers. Although they seem to be missing the defines needed to manage
desktop GL contexts.

Include them for now to fix the build as mentioned in github issue #31.
Tested against version 304.125, although later should also be ok.
