thor: Allow 1.2 to stay compatible with ancient facter

For people bundling various tools from the ecosystem in a container,
lets say https://github.com/voxpupuli/container-voxbox, we want to /
have to stay compatible with facter for now. The
ancient/dead/unmaintained Perforce facter gem depends on thor < 1.3.
