Fix RHEL 8 names

[Obihoernchen]

A .0 patch level is actually part of the name in RHEL8. This is not the case for RHEL 9 though.

@Obihoernchen The PR test failed. Would you check on it?

We have seen this failure before from time to time.
Could never figure out why this happens.
We create a node group with mkdef, list the table entry for it, then try to lsdef it.
Intermittently the lsdef fails to list the group:

'RUN:mkdef -t group -o dyngrp -d -w cons==hmc [Mon Mar  4 03:00:53 2024]',
          'ElapsedTime:0 sec',
          'RETURN rc = 0',
          'OUTPUT:',
          '1 object definitions have been created or modified.',
          'CHECK:rc == 0	[Pass]',
          ' ',
          'RUN:tabdump nodegroup [Mon Mar  4 03:00:53 2024]',
          'ElapsedTime:0 sec',
          'RETURN rc = 0',
          'OUTPUT:',
          '#groupname,grouptype,members,membergroups,wherevals,comments,disable',
          '"abc",,"static",,,,',
          '"dyngrp","dynamic","dynamic",,"cons==hmc",,',
          ' ',
          'RUN:lsdef -s dyngrp [Mon Mar  4 03:00:53 2024]',
          'ElapsedTime:0 sec',
          'RETURN rc = 1',
          'OUTPUT:',
          'Error: [fv-az1434-559]: Could not find an object named \'dyngrp\' of type \'node\'.',
          'No object definitions have been found',
          'CHECK:rc == 0	[Failed]',

Yes looks like sometimes communication to xcatd is broken in Ubuntu. Successive runs of makedhcp are buggy, too.
I triggered a retest and it passed ;)
