gl-renderer: Skip non-dummy rbs in get_dummy_renderbuffer()

Browse source 
No backends currently create FBO or dma-buf renderbuffers on outputs
associated to a window. This is theoretically possible though and
should be allowed by the GL renderer. This commit prevents
output_get_dummy_renderbuffer() from mixing up renderbuffer types.
