[Buildroot] [PATCH 2/2] legal-info: add a comment about what pacakges we save the tarballs of

[Yann E. MORIN]

From: "Yann E. MORIN" <yann.morin.1998 at free.fr>

As the legal-info infra only (rightfully) saves the tarballs of packages
that:
  - we want to redistribute,
  - and are not local,
  - and are not overriden,

add a comment stating so.

This should clarify the code-block, which although trivial to read,
was not easy to interpret without thinking thouroughly about it.
