autotest: Rename wifi_android_correctness->wifi_correctness_cros_core

It is likely that we're going to test WiFi correctness on a number of
platforms that do not include shill.  The most obvious way to go about
this is to control wpa_supplicant directly, as the Android tests do.

BUG=None
TEST=None
