examples/dmabuf-capture: add extra roundtrip for wl_output listener
This example was relying on wl_display_dispatch being enough to fetch
output information. This worked by chance.
Add an explicit wl_display_roundtrip.
Other examples don't setup wl_output listeners, so they should be fine.
Fixes: ("Remove unnecessary wl_display_dispatch calls")
