rules: clean up stale CD drive mounts after ejection
Ejecting a CD with the hardware drive button only causes a change uevent, but
the device node stays around (just without a medium). Pick up these uevents and
mark the device as SYSTEMD_READY=0 on ejection, so that systemd stops the
device unit and consequently all mount units on it.
On media insertion, mark the device as SYSTEMD_READY=1 again.
