core/pkg-infra: prepare for alternate default source archives

Browse source 
The .tar.gz default extension is historical, and we initially used
to only fetch tarballs from remote sites.

When we introduced downloads from VCS repositories, we kept that
extension, and kept compressing with gz, by lack of good reason to
switch to some other compression scheme.

However, nowadays, we will want to change the way we construct the
tarballs we generate from VCS. This will de facto change the hashes
of those tarballs.

So we will want that the archives we generate do not clash with the
existing ones, so we need another filename. Thus, we need a way to
be able to use a different extension when we generate archives from
VCS.

Use a macro as suggested by Arnout.
