Mask out macRandomizationSetting when feature is unsupported

All wifi networks will use factory MAC to connect when the
config_wifi_connected_mac_randomization_supported feature flag is set to
false.
Making macRandomizationSetting always return "false" in the above case.

Bug: 137230966
Test: unit tests
Test: manual test on a unsupported device - verifying network details
page is always showing the factory MAC address.
