init.d/cman: use fence_tool -m for two node clusters

bz 460190

Use the new fence_tool -m option in the cman init script for two node
clusters.  This delays fence_tool join when both nodes aren't members.
The delay allows initial cluster partitions (due to badly configured
network/switches) to converge before starting fencing.
