Add release script option for tarball files

Tarballs have two main advantages for releases:
- they contain translations
- they do not require a Bitbake roundtrip to the git server, which is
  important of sstate caching and reproducible builds (when using a tag
  instead of a hash, Bitbake resolves the tag on each build)

The current script version expects that the sha256 values are checked
against the respective release.
