Revert "Merge pull request #2125 from melissaanne/ticket/stable/re-597-a...

...dd-f20"

The rest of the fedora 20 stack was not built up yet, so builds against fedora
20 were failing. This revert can be reverted when facter, ruby-rgen, and hiera
are built and available in the fedora 20 yum repositories.

This reverts commit ae173d8f78da375718a8d1e1c2bd65a60615f5d7, reversing
changes made to 710e16780e64c436090c27ce6315d7cd5747cd41.
