TOKITA Hiroshi b2b0901c0d samples: sensor: change to use the app.overlay file 
The DTC_OVERLAY_FILE variable is specified on the command line.
It's not preferable to set it in CMakeLists.txt.
The app.overlay file is used as the default overlay file, so use it.

ams ens210 Relative Humidity and Temperature Sensor
###################################################

Overview
********

This sample application demonstrates how to use the ams ens210 sensor to
measure the ambient temperature and relative humidity.

Building and Running
********************

This sample application uses the sensor connected to the i2c stated in the
app.overlay file.
Flash the binary to a board of choice with a sensor connected.
For example build for a nucleo_f446re board:

.. zephyr-app-commands::
   :zephyr-app: samples/sensor/ens210
   :board: nucleo_f446re
   :goals: build flash
   :compact:
