WilliButz f412df1f6b nixos/prometheus-postfix-exporter: set default group
The postfix exporter needs to access postfix's `queue/public/` directory
to read the `showq` socket inside. Instead of making the public
directory world accessible, this sets the postfix exporter's group to
`postdrop` by default, when the postfix service is enabled.
