synch targets: ensure wants relationship

Synchronization targets (i.e. targets that do not have services
underneath them) require "Wants" relationships to ensure they are
started and utilized. In most cases a service using them as a
synchronization target will ensure they are started but to be sure,
this should be explicitly defined within the targets themselves.
