[build] Use $(xxx_DEPS) for additional dependency information
Some objects (embedded.o, rootcert.o, and clientcert.o) define
additional dependencies on external files, using syntax such as:
$(BIN)/clientcert.o : $(CERT_LIST)
This dependency can be missed when using debug builds. For example,
if DEBUG=clientcert is used, then the relevant object is
$(BIN)/clientcert.dbg1.o rather than $(BIN)/clientcert.o.
Fix by adding dependencies to $(clientcert_DEPS) instead:
clientcert_DEPS += $(CERT_LIST)
