agent: Split component_free() into component_[close|free]()

Closing a component and freeing it are slightly conceptually different.
As it happens, freeing it can result in the disposal of the component's
NiceIOStream, which requires the agent lock to be released — but closing
the rest of the Component requires the agent lock to be held. Splitting
the function up simplifies locking handling in other parts of the code
(see next commit).
