(factory-2305.B)Fix for light sensor device path

Default path will be set as
/sys/bus/iio/devices/device0/illuminance0_input. If test_list has an
argument of "device_path" then it will find the light sensor at
designated location as below:

    OperatorTest(
        autotest_name='factory_LightSensor',
        label_zh='光感應器',
	dargs={'device_path':'/sys/bus/iio/devices/iio:device0/'}),

BUG=chrome-os-partner:9725
TEST=factory light sensor test should be started
