tools: add openssl-cli to macos-firewall.sh

Currently, there is a new popup asking to accept incoming connections
for openssl-cli when running tests on macos. I believe the reason
for this not being noticed before is that test-tls-securepair-client.js
was moved recently from the pummel directory to sequential.

This commit adds openssl-cli to the firewall script.
