DSM_HOSTNAME does not get passed anymore
### Describe The Bug

Running DSM 7.1.1 with latest docker
homebridge version 1.6.0
package version 1.0.33

after i upgraded to DSM7 and installed the lateest homebridge version i noticed that DSM_HOSTNAME does not get passed anymore
after the container has started the name is still homebridge.
this results in an error
`hostname: No address associated with hostname`
everything is working like it should exept for the hostname error

when i login to the container and type env the result for DSM_HOSTNAME=DISKSTATION.
so it is active inside the container but it is not translated back to the hostname

looks like an old problem
https://github.com/oznu/docker-homebridge/issues/365

ENABLE_AVAHI is set to 0
i also tried 1 but this does not fix the problem


### Docker Config

```yml
DSM_HOSTNAME=DISKSTATION
```
