program loading: add optional is_loader_active() callback

Add a way for a loader to indicate if it is active. Such users
    of this callback would be vboot which can indicate to the rest
    of the system that it isn't active. is_loader_active() also
    gives vboot a chance to perform the necessary work to make
    said decision.
