fix(tools): corda AIO supervisorctl configuration

While trying to use the supervisorctl binary
to manage the starting of the corda-network
process configured in supervisord.conf the
following error was encountered and then
fixed by this change:

$ supervisorctl -c /etc/supervisor/supervisord.conf
Error: .ini file does not include supervisorctl section
For help, use /usr/bin/supervisorctl -h
