glx: glX_proto_send.py: use correct compile guard GLX_INDIRECT_RENDERING

The code itself has nothing to do with shared glapi, thus having it
behind GLX_SHARED_GLAPI is misleading. Use GLX_INDIRECT_RENDERING
instead.

The latter macro is set at global scope by the Autotools and Scons build
systems.
