setup module, retry facter to handle --puppet errors (#80645)

* setup module, retry facter to handle --puppet errors

facter versions have changed how they deal with the --puppet flag
when puppet is not present, most versions will just ignore it and not error,
but initial versions of facter 4 changed the behaviour (later reverted).

fixes #80496
