    Instead of using two dummy views to centre the keys, have the
    centre LinearLayout use margins instead.

    Fix uneven spacing of navigation bar buttons in landscape

    * Add two dummy views to the left and right corners to
      bring the buttons nearer to the center
    * This makes it easier to hit the back and recents key,
      and makes it identical to what the Sony firmware has.

    Same as commit 'd2af20ff1077b2edbc85160dde94db809dbf3643',
    but for landscape
