[mod] docker-entrypoint.sh - add script to make test.sh (shellcheck)
Add script docker-entrypoint.sh to shellcheck and try to _simplify_ and _normalize_ some parts: - fix issues reported by shellcheck - don't mix tab and space indent - command 'help' replaced by '-h': ./dockerfiles/docker-entrypoint.sh -h - replace printf in help() by 'cat <<EOF' Signed-off-by: Markus Heiser <markus.heiser@darmarit.de>
