_damo_records.poll_target_pids(): Return False if there's no real thing to do
__poll_target_pids() is for both adding child processes to targets and
checking if the target processes are terminated. However, the target
processes termination check is done by waiting for kdamonds termination.
Skip unnecessary work if not requested.
