[stable/jenkins] fix parsing java options (#10140)

Java options are stored in env var JAVA_TOOL_OPTIONS however the
entrypoint shell script of the docker image expects them in env var JAVA_OPTS

  # read JAVA_OPTS and JENKINS_OPTS into arrays to avoid need for eval (and associated vulnerabilities)
  java_opts_array=()
  while IFS= read -r -d '' item; do
    java_opts_array+=( "$item" )
  done < <([[ $JAVA_OPTS ]] && xargs printf '%s\0' <<<"$JAVA_OPTS")
