Sets the rotation source as USER when using the system display API

Sets the rotation source as USER when using the system display API

The rotation preference is not persistent across reboot since we only
store the preference if the rotation source is 'USER'. With the move to
MD settings, we now use the System Display API to update any display
settings, which still uses the source of rotation as ACTIVE.

This change updates the source of rotation to USER. We persist the
setting even if the change has been made by an application. (This is 
consistent with the other settings that are being set via this API.)
