commit 5976fded9494bbb08e15c5ab6736f3bdfd8058ac
Author: NAKAHIRA Kazutomo <nakahira@intellilink.co.jp>
Date:   Thu Feb 18 15:23:32 2016 +0900

Fix: libservices: Check resource agent is executable or not before pipe open.
    Currently, if lrmd execute resource operation and resource agent does not exist, then pipe does not closed.
    It waste 4 file descriptors each resource operation.
