core/pkg-infra: prepare for alternate default source archives
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. Signed-off-by: "Yann E.
