tools/ceph_monstore_tool: include mgrmap in initial paxos epoch

before this change, the "mgr" map is not included paxos, thus why the
peon mon fails to have the mgr map after it is sync'ed with its leader.
and hence there is chance that ceph-mgr is unable to get a mgr map from
the monitor it is connected to.
