add browsers-file to goan_config if ENABLE_BROWSERS_LIST true

- If the user sets the env variable `ENABLE_BROWSERS_LIST` to true, their `goaccess.conf` file is modified to include the `browsers-file` which points to the `/goaccess-config/browsers.list` file.
- In the event that the user's `goaccess.conf` file already references a `browsers.list` file, the `/goaccess-config/browsers.list` file is ignored in favor of the user's file.
