After obtaining some help from the #bash channel on Freenode IRC, it 
appears that the correct fix would be to use proper string substitution in 
the rabbitmqctl script:

Replace this line:\
    su rabbitmq -s /bin/sh -c "/usr/lib/rabbitmq/bin/${SCRIPT} ${CMDLINE}"

With this line:
    su rabbitmq -s /bin/sh -c 'script=$1; shift; "$script" "$@"' _ 
"/usr/lib/rabbitmq/bin/${SCRIPT}" "$@"

Credit goes to user zendeavor of the #bash channel on Freenode IRC.

Best Regards,
Kal
