brightboxImage: remove, as it seems unmaintained (#339790)

- The `antennas` package and the `services.antennas` module have been

  removed as they only work with `tvheadend` (see above).

- The `system.build.brightboxImage` image has been removed as It did not build anymore and has not seen any maintenance in over 7 years (excluding tree-wide changes).

- The `services.syncplay` module now exposes all currently available command-line arguments for `syncplay-server` as options, as well as a `useACMEHost` option for easy TLS setup.

  The systemd service now uses `DynamicUser`/`StateDirectory` and the `user` and `group` options have been deprecated.
