Subject: [PATCH] nixos/graylog: add option dataDir

in order to use this nixos module with Graylog 6.0, in which

> the default value for the data_dir configuration option has been
> removed and must be specified in graylog.conf [1].
> -- https://go2docs.graylog.org/current/upgrading_graylog/upgrading_to_graylog_6.0.x.htm

The value set by default is the same as before introducing this option.
