[Buildroot] [git commit branch/next] core/legal-info: install source archives in their own sub-dir

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=de2f89edd389e655fd705ea7c9d367878a6719ac
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/next

Currently, we put all source archives side-by-side in the same
directory.

Since we're about to also save individual patches that were applied
on those sources, we don't want to make that directory a complete
mess of unassorted files.

So, we install each source archive in its own sub-directory, where
we'll later store the patches too. Store that location in a variable,
so it can be re-used later on (to install patches in a future commit).
