CtsVerifier / Camera video test: Remove the fixed screen orientation property.

This property has been set on the camera video activity since 2012, before foldables existed. When
operating in multi-window mode, the app will not remain in one orientation and so this property has
no effect. We need the activity to be recreated in order to correctly display the camera preview,
which does not happen with this property set. Therefore removing it seems to be the right course of
action.

Test: Ran camera video activity in all screen orientations / folded and unfolded.
