overlay: Disable SystemUI anti-falsing on lockscreen

 * The anti-falsing implementation from HumanInteractionClassifier
    regularly prevents easy swipe to unlock or to pattern / pin
    on the keyguard lockscreen, requiring multiple attempts
    until accepted due to a hardcoded evaluation (5.0f)
    while normal usage shows better results without it

 * Another solved situation is remote device access like
    Vysor or TeamViewer where the device is almost impossible
    to swipe properly from a computer client
