rc: add support for scanning USE_PROCD and skip running if not supported

Browse source 
Running check is supported only in procd scripts. This cause prolonged
execution time since the function needs to timeout.

To fix this check if the script USE_PROCD and run running check only if
supported.

Also provide running info only if the running check is supported.
