I just noticed that handle_expr callback of json_script_ctx was never
actually used.  In the specific case of hotplug events handling of
procd, we can just add a 'isdir' '/etc/hotplug.d/%SUBSYSTEM%' expr and
do the hotplug-call accordingly.  Well, now this needs to fix libubox
first so cc-ing Felix.
