BuildChefAppbundle#appbundle_gem

appbundle the gem, making /opt/chef/bin/<binary> do the superfast pinning
thing.

To protect the app from loading the wrong versions of things, it uses
appbundler against the resulting file.

Relocks the Gemfiles inside the specified gems (e.g. berkshelf, test-kitchen,
chef) to use the distribution's chosen gems.
