Improved keychord logging.

Often a bugreport is accidentally triggered by the combo keys, but there
is nothing in the bugreport to confirm that action because init's
klog level is KLOG_NOTICE_LEVEL.

This change change keychord's INFO messages to NOTICE, and also logs the
case where a service was not launched because ADB was disabled.
