randr: hook up output slave to screen resources return 

When the client asks for the screen resources list, it will now
get a list of crtc/outputs for the master + all attached slaves,
this will let randr configure all attached slave devices properly.

Keith asked I merge the two functions, but not just yet, the current
multi screen code doesn't handle primary yet properly, will fix it up later.
