[PATCH 6/8] test-stkutil: Add unit test for Get Inkey response encoding.

Hi Andrew,

There is no need to define these as static variables will be initialized to zero automatically. We must guarentee zero means non-existence. 
If some meaningful initialization happens to be missed, later check would catch them. Hope this can save several lines of code;)
