kasli_tester/zotino: always alternate voltage sign 

Before the voltages on a second Zotino would start 2.1, 1.9, 2.2, 1.8
..., 3.6, 0.4 and overlap with the voltages on the first.
Now the voltages are 2.1, -2.1, 2.2, -2.2, ..., 3.6, -3.6 which allows
quick identification of card/channel and easy prediction when deploying.
