Incorrect/incomplete autorequire in cs_primitive type

[fghaas]

cs_primitive has an autorequire against the corosync service.

This makes no sense except when are running with corosync::service { 'pacemaker': version => 0 }; under all other circumstances the autorequire should be against pacemaker. For context, see also #143.
