[Arnout Vandecappelle (Essensium/Mind)]

commit: https://git.buildroot.net/buildroot/commit/?id=c1723424b8189730087006fc879fdae0cc123ca1
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Add 7za stand-alone executable as 7zr is a "light-version" of 7za that
only handles 7z archives and cannot handle encrypted archives.
