Reintroducing the logging::Manager's Terminate() method.

It doesn't do anything else than simply forwarding to FlushBuffers().

This is just for consistency in terminate_bro() where components get
their Terminate() called so that the main code doesn't need to know
anything more specific about what particular action to take at
shutdown.
