Remove cruft

I think that "IT'S NOT A HACK, IT'S A FEATURE! WHEEEEEEEEEEEE!" might be a code smell. ;)

This removes puppet::package::patches (are you freaking kidding me, github?) which went and changed core puppet / facter to fix bugs. I get why it was necessary at the time, but they're old versions that people shouldn't be running any more.

Also removes the Fedora 18 beaker node definition. There are a bunch of ones that are unlikely I'll use (SLES?) but Fedora 18 I'll definitely for sure never test against.
