refactor(tvix/castore): move gRPC directorysvc tests off tonic_mock r/6725

The tests were using the gRPC Service/Server interface, not the gRPC
clients.

Use our new gen_directorysvc_grpc_client() function to spin up a server
in a separate thread, and test via that client, rather than *just* the
server implementation.

This is more correct, because we're now really exercising the gRPC
stack, and some of the stream implementations are also only implemented
on the client.
