Bug#926558: Cleanup of /doc/ddp

[Thomas Lange <lange@informatik.uni-koeln.de>]

It would be great if someone can check the link to DDP-BR on
/doc/ddp. For me it seems DDP-BR also is outdated. The wiki lists a
Debian release from 2015.
Looking at "Documentos" it see a lot of links not working. Also
several links under those sections reply with "Server not found":

Documentos feitos em casa
Documentos traduzidos

IMO we can remove this sentense including the link on /doc/ddp:
"Note to Portuguese-speaking users: visit DDP-BR, web pages about localization of Debian documentation in Brazilian Portuguese language."
