Subject: [PATCH 1/2] udev: ensure that all events relating to device are
 tagged systemd

systemd will not restart the usbmuxd service the after the first time it
is plugged in if it does not receive the "remove" events, which also
happen to lack the idVendor and idProduct attributes, so use
ENV{PRODUCT} instead.
