tests/acceptance/integratorcp: Verify Tux is displayed on framebuffer 

Add a test that verifies the Tux logo is displayed on the framebuffer.

We simply follow the OpenCV "Template Matching with Multiple Objects"
tutorial, replacing Lionel Messi by Tux:
https://docs.opencv.org/4.2.0/d4/dc6/tutorial_py_template_matching.html

When OpenCV and NumPy are installed, this test can be run using:

  $ AVOCADO_ALLOW_UNTRUSTED_CODE=hmmm \
    avocado --show=app,framebuffer run -t device:framebuffer \
      tests/acceptance/machine_arm_integratorcp.py
