Our environment is a TFS 2013 server (12.0.21005.1 Tfs2013.RTM) which was upgraded from a fresh installation of TFS 2008, with a number of team projects and developers.
The permissions that you show above are for Team Projects and not builds.
If you select a build and right-click on it you should get a permissions option. Here you will find build specific permission that you are looking for.
You can also set permissions through the API with PowerShell...
