These test cases depend on setting up the existing hostapd instance to a
set of known addresses, which might be different from what test-runner
sets. During this time, any scans might result in the old and the new
addresses used by hostapd to be found in the scan results.
Fix that by using start_iwd=0 which tells test_runner that the test
wants to start iwd itself. This delays starting iwd until after the
setUpClass routine has been called and hostapd configured properly.
Also use more sensible rssi values for the 'non-preferred' bss.
Otherwise, ranking BSSes by throughput can confuse the test logic
since both BSSes are ranked the same and either can be picked by
autoconnect.
After the test-runner re-write many tests were left with
stale options that are no longer used at all. These were
periodically getting removed as changes were made to
individual tests, but its apparent now that a tree wide
removal was needed.
