Add -u/--user to force running as a user service manager.

Since running as root now runs as a system service manager by default,

Set control_socket_open false when closing the socket.

If we booted to single-user mode, we close the socket once it exits, so
we need to open it again. Leaving control_socket_open true means that we
don't do that, so set it false.
