Using $id to get the rcX device name from the SUBSYSTEMS match,
as used by the upstrem v4l-utils udev rule, is easier and more
stable than using IMPORT{parent}, which needs to transmit info across
two levels (rcX->inputY->eventZ) and breaks with kernel 4.20.
Instead of running a shell script to check for the existance of
/storage/.config/rc_maps.cfg we can use the builtin udev TEST
function.
Also it's better to use ENV variables prefixed with a dot as
they are used only locally in the udev rule file and don't need
to be persisted in the udev database or exported to external tools.

ir-keytable -a can fail if it's run before the input and event
devices are created. Fix this by changing the udev rule to trigger
on event device creation instead of rc device creation.
Also drop the udev rules patch and simply replace the udev rule
with our version, this is easier to maintain.
