backend/drm: stop force-probing connectors
After discussing with Pekka and Daniel on #dri-devel, we concluded [1]
that user-space shouldn't need to force-probe connectors. Force-probing
can take some time, so using drmModeGetConnectorCurrent can result in
faster start-up.
Users can manually trigger a force-probe if necessary:
echo detect | sudo tee /sys/class/drm/card0-DP-1/status
Or just by running a tool like drm_info.
A similar change has been submitted to Weston [2].
