package/pkg-utils: add vendoring mechanism into generated archive filename
When we change the way we vendor packages, either because our download
backend or helpers evolve, or when the vendoring tools themselves change,
we must avoid generating new archives with the same name, or there would
be confusion when using older archives with newer Buildroot versions, or
the other way around (and that would mess with local caches, like the
one we share on s.b.o).
This is going to be the case for example, when we enforce a better and
more reproducible set of modes on archived files in the following
commits.
Introduce a version suffix for post-processed downloads, that we can
bump when needed.
