Subject: test: make SSH_PORT overridable in test-install.sh

The port was hardcoded, so a test run collided with any other VM already forwarding 2222. It now defaults to 2222, so existing invocations are unchanged. SSH_PORT=2223 scripts/test-install.sh picks a free port to run alongside another VM.
