Fix sunrise output filename to reflect SUNRISE_TARGET_SECS from conf

The output video was always named -sunrise-10s.mp4 regardless of the
configured duration. Both sunrise_video.10s.sh and sunrise2mm.py now
derive the filename from SUNRISE_TARGET_SECS so changing it in conf
produces correctly named files that the uploader still finds.
