{tvheadend,antennas}: drop (#336395)

  were not used by any other package. External users are encouraged to

  migrate to OpenCV 4.

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

  removed as nobody was willing to maintain them and they were stuck on

  an unmaintained version that required FFmpeg 4; please see [pull

  request #332259](https://github.com/NixOS/nixpkgs/pull/332259) if you

  are interested in maintaining a newer version.

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

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