tests/avocado: update the tcg_plugins test

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 ea185a5
  - log total counted instructions/memory accesses
