Missing copyright notices for shaded packages

From discussion on dev@, it was recently discovered that we are missing copyright notices for packages that we are shading.

The recommended fix from davor (see linked conversation), is:

I'd suggest appending this sentence to the end of the LICENSE file: "A part of several convenience binary distributions of this software is licensed as follows", followed by the full license text (including its copyright, clauses and disclaimer) – for each such case separately. Don't edit the NOTICE file.
