Allow overriding $CLI outside test scripts

this will allow you to test against installed RPM like so:

    # export CLI="/usr/bin/composer-cli"
    # make test_images

If you already have lorax-composer running then you can directly
execute test scripts:

    # ./tests/cli/test_build_and_deploy_aws.sh
