glx: Only compute client GL extensions for indirect contexts

Browse source 
This is sort of a spiky way to do it, but the effect is to send the
appropriate SetClientInfo twice for indirect screens, where the second
one fills in the GL extensions. We can get away with this because the
only place the string is used is when the server computes the reply for
glGetString(GL_EXTENSIONS), which never matters for direct contexts.
