tests: Change most SAE test cases to use suitable groups
Reduce testing dependency on the unsuitable groups so that a test case against a production build would not fail the test case unnecessarily. This is in preparation of making production builds (CONFIG_TESTING_OPTIONS not defined) of wpa_supplicant hostapd disable all DH groups that have been indicated as being unsuitable.
