Force Kids app to use LANDSCAPE when in REVERSE_LANDSCAPE

A few apps in Kids Space request "reverseLandscape" orientation when
Display#getRotation returns ROTATION_270 expecting it to correspond
to the seascape display orientation while it may correspond to the
landscape one when config_reverseDefaultRotation is set to true.

This CL overrides the "reverseLandscape" orientation with "landscape"
in the context of apps running in the Kids space when
config_reverseDefaultRotation is set to true
