Gerard Marull-Paretas c7b5b3c419 samples: migrate includes to contain <zephyr/...> prefix 
In order to bring consistency in-tree, migrate all samples to the use
the new prefix <zephyr/...>. Note that the conversion has been scripted:

```python
from pathlib import Path
import re

EXTENSIONS = ("c", "h", "cpp", "rst")

for p in Path(".").glob("samples/**/*"):
    if not p.is_file() or p.suffix and p.suffix[1:] not in EXTENSIONS:
        continue

    content = ""
    with open(p) as f:
        for line in f:
            m = re.match(r"^(.*)#include <(.*)>(.*)$", line)
            if (m and
                not m.group(2).startswith("zephyr/") and
                (Path(".") / "include" / "zephyr" / m.group(2)).exists()):
                content += (
                    m.group(1) +
                    "#include <zephyr/" + m.group(2) +">" +
                    m.group(3) + "\n"
                )
            else:
                content += line

    with open(p, "w") as f:
        f.write(content)
```

DHT: Aosong DHT Digital-output Humidity and Temperature Sensor
##############################################################

Description
***********

This sample application periodically (0.5 Hz) measures the ambient
temperature and humidity. The result is written to the console.

Wiring
*******

This sample uses an external breakout for the sensor.  A devicetree
overlay must be provided to identify the sensor variant and the GPIO
used to control the sensor.

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

After providing a devicetree overlay that specifies the sensor location,
build this sample app using:

.. zephyr-app-commands::
   :zephyr-app: samples/sensor/dht
   :board: nrf52dk_nrf52832
   :goals: build flash
