Update rabbitmq

Changes:

- https://github.com/docker-library/rabbitmq/commit/ece63d4: Merge pull request https://github.com/docker-library/rabbitmq/pull/511 from infosiftr/jit-arches
- https://github.com/docker-library/rabbitmq/commit/c0bec38: Only test i386 on Alpine builds (no support for Ubuntu on i386 anymore and qemu-user-static is way too slow on GitHub's runners)
- https://github.com/docker-library/rabbitmq/commit/b596ec7: Adjust "--enable-jit" to be properly conditional
