Make the engine config module always add dynamic ENGINEs
to the list using dynamic_path. This stops ENGINEs which
don't supply any default algorithms being automatically
freed (because they have no references) and allows them
to be accessed by id.

Alternative dynamic loading behaviour can be achieved by
issuing the dynamic ENGINE ctrls separately in the config file.
