tracemalloc: 'pretty top' example no longer changes the filename (GH-18903)

I've used this recipe a couple times and the filename editing has always been less than useful and something I've removed. This is because many modules end up losing which package they are located in, e.g. `util/date.py`. (cherry picked from commit d06eec2) Co-authored-by: Adam Johnson <me@adamj.eu>
