Small tweak to run a golang example app on run.pivotal.io

Hi there,

Thanks for a most awesome work on cf.

I did get to deploy a golang app here: http://gocf.cfapps.io/
Here is the small patch on the top of your changes that I needed.

Here is the example app source code and manifest.yml:

Is there a way to send dot files like '.godir' with cf?
That would enable us to stick to the original buildpack a little more.

Cheers!
