sysutils/goss: create port

Goss is a YAML based serverspec alternative tool for validating a server's
configuration. It eases the process of writing tests by allowing the user to
generate tests from the current system state. Once the test suite is written
they can be executed, waited-on, or served as a health endpoint.
