Jouni Malinen 9aa82da229 tests: Make ACS tests more reliable 
The test cases that used country code ZA for the actual test on the 5
GHz band ended up failing in some cases due to various race conditions
with the initial AP start on the 5 GHz band using country code US.
Reduce the risk for that type of failures by using the same country code
ZA for both AP starts.
