Github-generated tarballs are known to change over time, so use an archive tarball provided by zlib.net instead.

2.13.5

Looks like a good idea but the maintainer removes the old releases:

The moment a new tarball comes out we'll need to fix all previous oe-core releases... maybe the author has a secret directory of all releases, or could be talked into not deleting future releases?
