Subject: [PATCH] Use `openssl@3` when building on macOS

There is an issue building a project depending on `swift-kafka-client`
on macOS, with `libressl` installed. Explicitly switching to `openssl`
on macOS remediates the issue with all tried combinations.

Resolves https://github.com/swift-server/swift-kafka-client/issues/191

 `librdkafka` depends on `openssl`, meaning that `libssl-dev` must be present at build time.
