Error: could not get uid/gid
After starting Homebridge, I have this error.
I don't know what this can affect, as Homebridge seems to work nonetheless.

```js

FYI, I'm using an [`aarch64` image](https://github.com/oznu/docker-homebridge/issues/91).

I think the UID/GUID are what they should be:

```sh
pi@nanopineo2 ~/homebridge> id
uid=1000(pi) gid=1000(pi) groups=1000(pi),20(dialout),27(sudo),29(audio),44(video),46(plugdev),101(systemd-journal),109(netdev),112(ssh),999(docker)
```

This is my `docker-compose.yml`:

```yaml
version: '2'
services:
  homebridge:
    image: oznu/homebridge:aarch64
    restart: always
    network_mode: host
    volumes:
      - ./config:/homebridge
    environment:
      - TZ=Europe/Paris
      - PGID=1000
      - PUID=1000
      - HOMEBRIDGE_CONFIG_UI=1
      - HOMEBRIDGE_CONFIG_UI_PORT=8080
```

Full log:
