perf python: Convert tracepoint.py example to python3

Browse Source 
Convert the tracepoint.py file to python3 as many of the files in
tools/perf are already written in python3.

Committer testing:

  # export PYTHONPATH=/tmp/build/perf/python/
  # python3 ~acme/git/perf/tools/perf/python/tracepoint.py | head
