* in order to appbundle inspec-core-bin we need a Gemfile.
* the previous gemfile refers to inspec-bin and that gets packaged and
shipped with the inspec-core-bin Gemfile and that does not work when
appbundler tries to use it.
* hacking up appbundler to be more complicated than it is, is probably
a poor idea since it is already a big pile of magic.
* so what would be good to do in order to preserve the DRY'ness of
having both inspec-bin and inspec-core-bin share binaries, would be to
have the Gemfile be usable by both gems when they are ultimately
consumed.
* because the inspec-core-bin gem only has the inspec-core-bin.gemspec
what we can do is test to see which gemspec we have and then behave
accordingly.
still a bit hacky, but better than the other alternatives we considered.
