systemui: Fix the TrustDrawable animation state

 * The TrustDrawable animation is being mistakenly activated when
   the screen turns off, resulting in SystemUI obliterating
   SurfaceFlinger with vsync requests. This results in high power
   consumption.
 * Add a check for device interactive state when enabling the
   animation to prevent this.
