CameraITS: Modify setting of capture on test_unified_timestamps

test_unified_timestamps always uses manual capture settings
even if device does not have MANUAL_SENSOR capability.
Therefore this test case always fails on such device.

If device doesn't have MANUAL_SENSOR capability, test case case
uses auto capture settings.
