[PATCH] dracut-module-setup: allow short hostname in cluster configuration

[WANG Chao]

Node could be referenced by short hostname (hostname -s) in cluster
configuration:

[root@virt-068 /]# pcs status nodes
Pacemaker Nodes:
 Online: virt-066 virt-067 virt-068
 Standby:
 Offline:

We didn't know it before. Martin noticed the kdump failure, and provide
this fix. Thanks to Martin.
