Support of the start from upstart of crm_mon.

It supported upstart in crm_mon.

However, I was not able to understand whether changes of the spec file were enough.
Please confirm my change, and please give me comment.

Yes.
When crm_mon starts earlier from pacemaker and does not stop later from pacemaker, a trap may not fly.
We wish a trap does not lack if possible.
