mpv unit: wait for udev/DRM devices before starting

Browse source 
Cold-boot race could leave mpv running but not rendering to HDMI (console
stays visible) even though the same command works when run manually later.
Order the unit after systemd-udev-settle so /dev/dri/* exists first.

# Wait until udev has settled so the DRM/HDMI devices (/dev/dri/*) exist
# before mpv tries to grab the display. Without this, a cold-boot race can
# leave mpv running but never rendering to HDMI (you see the console instead),
# even though the exact same command works when run by hand later.
