ServiceFrameworkBase: remove ownership to ServerPort

This causes a reference cycle because ServerPort also holds a shared pointer to SessionRequestHandler (inherited by ServiceFrameworkBase). Given that the member port is never used in ServiceFrameworkBase, we can simply remove it. The port object is kept alive by ServiceManager|KernelSystem::named_ports -> ClientPort -> ServerPort
