Don't use SetShape() to round the Findbar views widget corners.

Don't use SetShape() to round the Findbar views widget corners.

Now that views widgets can be rendered with transparency there is no
need to shape the widget for the visual effect, and the impact on hit-
testing is negligible, so there's really no point shaping the widget.
