[RFC PATCH] tests/avocado: update the tcg_plugins test

["Alex Bennée" <alex.bennee@linaro.org>]

There are a number of things that are broken on the test currently so
lets fix that up:

  - replace retired Debian kernel for tuxrun_baseline one
  - remove "detected repeat instructions test" since ea185a55
  - log total counted instructions/memory accesses
