fixes #2342 converting to ::osfamily to support redhat based distributio...

Removed the checks for every redhat variant, set the check to ::osfamily, removed the double check for Ubunto under the Debian check and also changed the not supported from ::operatingsystem to ::osfamily. This should allow all RedHat based OS's including Oracle Linux to install with latest facter showing the correct ::osfamily.

Sorry for all of the pull requests/withdrawls. I'm a little green on my git hacking and messed up my prior submissions.
