multi-backend: do not expose internal renderers

Browse source 
backend_get_renderer() is now returning the renderer of the primary GPU, instead
of its own renderer, since that's the thing which actually does all of the "real"
rendering

wlr_multi_backend_add() is now adding all subbackends (otherwise only one GPU
is handled).
