Work around nested SaveLayerAlpha bug

bug:11481077

Because TextView marquee and KeyguardSecurityViewFlipper use SaveLayer
(for the marquee fading effect and view alpha, respectively), both can
be nested, which hits a bug in the renderer resulting in artifacts.

Workaround this by setting a hardware layer on the marquee, so that
those marquee effects are drawn outside of the ViewFlipper.
