Cert provisioning script `generate-certs.sh` incorrectly copies the entire TLS "result" directory instead of the certs themselves.

This line is wrong:

Docker-RabbitMQ/rabbitmq/provisioning/generate-certs.sh

Line 19 in 7ce9bc9

cp -r result/ ../../../config/certs/

Should probably be the following, though it needs to be tested:

cp -r result/* ../../../config/certs/
