Bug(s) fixed: 153955

Bug Description: RPM install: A suffix must be a valid DN
Reviewed by: Noriko (Thanks!)
Fix Description: Rob found that the setup script did not work on his box.  It seems that there is no canonical way to get the FQDN.  So, this fix uses various different ways - hostname, hostname -f, hostname -a, and host `hostname` - and just uses the longest one, assuming it is the FQDN.
Platforms tested: RHEL3
Flag Day: no
Doc impact: no
QA impact: should be covered by regular nightly and manual testing
New Tests integrated into TET: none
