Always send setIgnoreDisplayTouches from UdfpsOverlayInteractor

Previously, we ignored sending setIgnoreDisplayTouches when the state
tracked in UdfpsOverlayInteractor did not change. In rare cases, this
state becomes out of sync causing a setIgnoreDisplayTouches call to be
missed. Avoid this by always sending setIgnoreDisplayTouches.
