Before this change, when I run `sudo rkt trust` it fails. I hope
we can also install rkt under usr/local/bin by default. So our
users can have a better experience when following our rkt basic
tutorial.
This issue was introduced by a recent script rewrote (#652)
Previously the vagrant configuration would grab the last release
of Rocket to build. Now Rocket will be built on whatever is in the
checked out git repository (/vagrant inside the VM)
This will allow testing of changes to Rocket using the "vagrant
provision" command.
It will also automatically use the latest rocket version.
Assumes ./build script handles cleanup.
Go and APPC versions still manually configured in provisioning scripts
