Bug#933728: cdimage.debian.org: missing files for debian-30r0-i386-binary

[Michael Paoli]

Also added the missing files, which have been (and sometimes are still
available) under
https://old-debian.balug.org/
to hopefully be more persistently and longer term available on
archive.org under:
https://web.archive.org/web/*/https://old-debian.balug.org/
