Fix intercepting touch events for guts

When guts are showing in keyguard, user's touch events
could be intercepted by ActivatableNotificationView
especially in notification header area.
And then, user had to touch buttons in guts twice to operate.
So, fix not to intercept touch events when guts are showing.

Test: Lockscreen > Swipe EXPANDABLE notification and
click snooze button > Try to click UNDO button or
expand button in snooze layout.
