Add support for releasing deblobbed u-boot 2020.07 source tarballs
Once the tarball are released, it will enable distributions to use these tarballs to produce deblobbed u-boot packages. Note that the produced tarball is not reproducible yet. Because of that it has to be trusted. During a release, it's a good idea to sign the uncompressed tarball as the various compression formats and associated tools make different tradeoffs. For instance with xz, xz -9e tends to compress really well with the the most used xz[1] implementation, and most GNU/Linux users probably already have it installed, but and the drawbacks is that the format is very fragile[2]. The lzip format is more suited for long term archiving but its most packaged implementation[3] is less likely to be already installed by users than more well known formats like xz, bzip2 or gzip. Being able to add more compression formats after the release is also useful, for instance to accommodate different build systems or use cases (like being able to build u-boot with less dependencies in distributions like Guix, or building u-boot directly on devices which don't have enough RAM for xz for instance).
