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:
So Tux > Messi??!! I knew that!

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
