Append the workspace name to the runfiles directory name (bazelbuild#856

) The runfiles directory is broken down by workspace name. This means that files belonging to the main workspace are placed at "${name}.runfiles/${ctx.workspace_name}/${short_path}". Files belonging to externals have a short_path starting with "../${external_name}". Because we currently don't append ctx.workspace_name to the computed runfiles path, files belonging to the main workspace are placed at the top level of the runfiles directory, which is incorrect. Even worse is that files belonging to external repositories end up alongside the runfiles directory, instead of being contained within.
