build instructions in README out of date - Missing godeps?

[nicobrevin]

Hi there.

It looks like the README's build instructions are out of date. The instructions to use godep are now redundant as of ac5bea8355bf8f1620d8504265ad286e60daa9b8.

I'm a complete go noob, but I managed to get the project to build once I moved my git clone to $HOME/go/src/twistlock-authz - only then did it pick up the vendor directory. Is this something that all golangers know?
