tests: Make flush_scan_cache() more robust

It was possible for BSS entries on the scanned channel (2412 MHz) to be
left behind after flush_scan_cache() call. Use a less likely channel
2417 MHz as the default channel to scan. This will hopefully get rid of
most problematic BSS entries from previous test cases. For example,
ap_hs20_oen followed by ap_hs20_random_mac could fail due to
INTERWORKING_CONNECT seeing non-RSN scan result from the previous test
case.
