I think the problem is that ir-sysfs.c checks for "rc5" before it checks
for "rc5sz". The "rc5" check passes on the "rc5sz" string and it never
gets to the "rc5sz" check.

For now, disabling the direction keys in the lirc key map is working
to prevent the double keys. This means that keys are coming though two
different interfaces, but it all works.
