relayd: rename viewer_session_set_trace_chunk and hide it

viewer_session_set_trace_chunk() is renamed to
viewer_session_set_trace_chunk_copy() as it creates a copy of the
source trace chunk before setting it on a viewer_session.

The function is also marked static as it is only needed within
the viewer-session.c TU.
