aziottpm user is not added to tss group list

[Dvergatal]

The below entry of /etc/group is created by current meta-iotedge receipes:

tss:x:987:

This is evidently missing aziottpm user connection and that is why we are getting such error:

After adding it with below command:

usermod -a -G tss aziottpm

I'm getting proper status for aziot-tpmd:
