Subject: [PATCH] fix(xcat-core): an openEuler node reinstalls for ever instead
 of booting

reg_linux_diskfull_installation_flat never finishes on openEuler. The install completes, the
postscripts run, and then the node reboots into the installer again and repeats, so the case waited
an hour and the node stayed at status=installing.

post.xcat.ng ends with updateflag.awk, the call its own comment calls the one that must always run
to prevent infinite installation loops. It passed $MASTER, a hostname. The anaconda %post chroot on
openEuler has no /etc/resolv.conf and no management node entry in /etc/hosts, so gawk cannot open
the socket. From the node's own /var/log/xcat/xcat.log:

  awk: /xcatpost/updateflag.awk:15: warning: remote host and port information
       (xcat58-mn, 3002) invalid: Name or service not known
  updateflag.awk: Retrying flag update

It retries ten times, gives up, and the status is never sent. Nothing reports it: the retry message
goes to logger, and a %post chroot runs no rsyslog.

The same script already uses $MASTER_IP for all 36 of its other callbacks, and the kickstart sets it
to the same host: MASTER_IP=192.168.58.1, MASTER=xcat58-mn. All six updateflag calls now use the
address, so none of them depends on a resolver the node does not have.
