Additionally, this can be running using testsuite. We have SingleTest
that can build (test_single_build) and run (test_single_run) any custom
machine.

To run avocado on host machine, previous fix should be followed by:

- Preparations:

python3 -m venv .venv/
. .venv/bin/activate
python3 -m pip install avocado-framework

- Running signle testcase:

avocado --show=app,test run --max-parallel-tasks=1
testsuite/citest.py:SingleTest.test_single_run -p machine=qemuamd64-iso
-p distro=bookworm -p image=isar-image-ci

This can be also run under kas shell in similar way, but some
additional packages should be installed:

- Preparations:

sudo apt update
sudo apt install qemu-system
sudo apt install python3-venv

python3 -m venv .venv/
. .venv/bin/activate
python3 -m pip install avocado-framework

Running both testcases from SingleTest class:

avocado --show=app,test run --max-parallel-tasks=1
/repo/testsuite/citest.py:SingleTest -p machine=qemuamd64-iso -p
distro=bookworm -p image=isar-image-ci
