perf test session_topology: Delete session->evlist

ASan reports a memory leak related to session->evlist while running:

  # perf test "41: Session topology".

When perf_data is in write mode, session->evlist is owned by the caller,
which should also take care of deleting it.

This patch adds the missing evlist__delete().
