[Buildroot] [PATCH 10/13 v2] core/legal-info: also save extra downloads

[Yann E. MORIN <yann.morin.1998@free.fr>]

Some packages, like perl, download extra files that end up as part of
the source that Biuldroot builds. Up until now, those files were not
saved in the legal-info output.

Add those files to the legal-info output.

The unfortnate side-effect is that we will also save the secondary
archive for the external blackfin toolchains; however, we already to
save the binary release of some external toolchains when they do not
provide actual source archives.

This is inherently bad, but solving this is a bigger concern, for
another series...
