Make a distinct rule to annotate composite-lifestages.owl.

As for composite-vertebrate.owl and composite-metazoan.owl, we need a
separate rule to create the composite-lifestages.owl product. The
generic rule 'composite-%.owl' is not enough because the standard
ODK-generated Makefile already contains a more specific rule, than can
only be overriden by an equally specific rule.
