Make SurfaceView layers captured by screenshotApplications()

Since SurfaceView layers are located below application layers,
SurfaceView is not captured by screenshotApplications()
when the application is running in fullscreen.

Moreover, ws.isFullscreen(dw, dh) returns mostly true
on the devices which do not use the navigation bar.
