  Changed script to explicitly use python3 only to avoid
maintaining python 2 and removed deprecation notice.

v5:
  - fixed python3 issue causing script to fail. Divisions without the
    typecast lead to a floating point result, which was messing up the
    loop.

v6:
  - Removed changes to mk/rte.sdktest.mk since it no longer exists.

It would be better to use the integer division operator: //
