additional landscape layout for sim pin unlock

- without this patch, if the phone is in car dock (landscape,
hw keyboard hidden), the sim pin unlock screen is cropped, making
it impossible to unlock the sim without taking the phone out from
the dock, which can be quite dangerous while driving. (You can be
presented with the sim pin unlock screen e.g. when the phone reboots
during navigation.)
