Print the location of trace chunk produced at session destruction

Print the location of trace chunk produced at session destruction

The destruction of a session that was rotated during its lifetime
will cause an "implicit" rotation to close the last trace archive.

This change makes the CLI client use the newly added destruction
handle interface of liblttng-ctl to print the location of the
last trace archive produced during the destruction of a session
(when applicable).
