lmp/bb-config: Add variable to debug CI_SCRIPT_DEBUG

[angolini]

This variable will enable bash trace mode to the ci-scripts so we can generate more log in case of a problem.

tested locally with a script that turn on/off the variable:

mkdir -p /tmp/lmp-archive /tmp/lmp-secrets
chmod 777 /tmp/lmp-archive /tmp/lmp-secrets

REPO_DIR=/tmp/lmp-manifest
if [ ! -d "$REPO_DIR" ]; then
    git clone https://github.com/angolini/lmp-manifest.git "$REPO_DIR"
fi
git -C "$REPO_DIR" checkout 13b7dd6a57b714e93cedad7f81fbaebbaf50f01c

docker run --rm -it \
    -v "$(pwd):/ci-scripts" \
    -v "/tmp/lmp-archive:/archive" \
    -v "$REPO_DIR:/repo" \
    -v "/tmp/lmp-secrets:/secrets" \

Wouldn't it be better to use a fork from this repo at the factory and modify it as needed?

If we need to add the CI_SCRIPT_DEBUG variable in the factory, it will be practically the same as configure a fork of the ci-scripts.

I also don't like this PR, I'm closing it. Found another way to debug it
