monitor-config-manager: Adjust accelerometer rotation for panel-orientation

The device orientation coming out of iio-sensor-proxy defines upright/normal
as the direction in which the picture is displayed on the LCD panel without
any rotation. This is necessary for accelerometer rotation to work properly
in desktop environments which are not aware of panel-orientation issues.

This means that we need to correct the logical-monitor-config / user-visible
rotation for the panel-orientation when we get rotation info from
iio-sensor-proxy.
