glx: add initial GLX_EXT_framebuffer_sRGB support.

this doesn't bind to drivers yet, just enough to in theory make indirect
work against other servers.

I'm really not sure what the rules for adding extensions to the known_gl_extensions list as it looks to be missing a few. are these GL extensions that have GLX
protocol??
