include Chef DLLs in the Habitat Windows packagerobb/reorder-gem-installs-in-hab-build

Chef needs some DLLs on Windows. Normally, the libraries get copied to
the directory where the current Ruby executable is located when
bundle install is run.

We don't want that in Habitat land. The Ruby executable lives in another
package and package namespace. We want the libraries included in *this*
package. So, here we copy the DLLs during plan build to a lib directory
within this package and set an environment variable to disable the copy
occuring during bundle install. We push the library path onto
RUBY_DLL_PATH to inform whichever Ruby interpreter that will be running
Chef where to find our DLLs.
