dbus: let session bus daemon manage user runtime dirs
Let the session dbus process manage user runtime directories (with
its own file type).
This is the fifth version (v5) of the patch, thanks to Dominick
Grift for revising the previous versions and suggesting improvements,
although unfortunately this new version needs to revert one of the
suggested amendments because it was misleading.
