Modify rotation test to use DBUS directly

On some NVidia cards, calling xrandr script to rotate the screen programatically may not work. Triggering screen rotation using DBUS directly is closer to what is done when the user manually modifies the rotation settings in the System Settings Display screen. We add a new script to handle this and modify the graphics rotation test job to use it.

+# rotation_test_using_dbus
+#
+# This script is used to trigger a main screen rotation directly from DBUS to
+# simulate the way screen rotation is done when using System Settings screen.
+# Indeed, when using xrandr command or Python lib, we sometimes have weird
+# behaviours, specifically when used with NVidia cards with proprietary drivers.
