Add a test demonstrating how one can embed various scripts in the
control DTB.
Verify that the source command can be used with ${fdtcontroladdr} by
itself (invoking the default script), and with :<node-name>
suffix. Check that the scripts themselves can invoke "sibling"
scripts. Also verify that without CONTROL_DTB_AS_FIT set, the control
DTB is not accepted by the source command.
