Since thread_exit() seems to be broken on iot-lab_M3 this is an important fix for tomorrow. ;)

The test randomly fails on `native` due to timers being not accurate but
it cannot be otherwise. So better disable it than raising fake errors.

    main(): This is RIOT! (Version: buildtest)
    Testing generic evtimer
    This should list 2 items
    ev #1 offset=1000
    ev #2 offset=500
    This should list 4 items
    ev #1 offset=659
    ev #2 offset=341
    ev #3 offset=500
    ev #4 offset=2454
    Are the reception times of all 4 msgs close to the supposed values?

18392: drivers/servo: reimplement with high level interface r=benpicco a=maribu

### Contribution description

The previous servo driver didn't provide any benefit over using PWM directly, as users controlled the servo in terms of PWM duty cycles. This changes the interface to provide a high level interface that abstracts the gory PWM details.

In addition, a SAUL layer and auto-initialization is provided.

### Testing procedure

The test application provides access to the servo driver via the `saul` shell command.

2022-08-02 22:12:45,351 # [servo] setting 0 to 6865 (255 / 255)
2022-08-02 22:12:45,354 # data successfully written to device #4
```

Each write resulted in the MG90S servo that I connected to move to the corresponding position.
