[Autofill Views] Compensating for rounded corners

The last footer row needs to include extra height/padding at the bottom
equal to the corner radius, to compensate visually for the rounding.
Currently we do include some padding at the bottom of the footer, but
it's outside the row, so we get some weird effects when we hover over
that row.
