pkg/testutils: default value for option.Config.HubbleLib

The testutils Config.TetragonLib (or in the end ConfigDefault.TetragonLib)
was never written to the actual option.Config.HubbleLib. We noticed it
was done manually all over the place in tests so this commit adds it in
TestSensorRun that runs in TestMain.
