Orogen does not include inherited ports when port_driven

[mmaurus]

Given Task A and Task B as follows:

task_context "TaskA" do
    input_port "portA"
end

task_context "TaskB", subclasses: "TaskA" do
    input_port "portB"
    port_driven
end 

then the updateHook of TaskB will only be triggered for portB, NOT for interited port portA!
In TaskBase::setupComponentInterface(), orogen did not add portA.
