Libhandy source is looking for 0.1 in downloads.gnome.org

The following discussion from !19 (merged) should be addressed:

This currently breaks the download script, cause it looks for libhnady on gnome.org but we are only hosting 0.80+ versions. Edited the version manually but it will break on next track as well. cc @akitouni

    if ext in versions[latest]:

I am expecting this is going to break the both stable convert-to-tarballs scripts for 3.34 and 3.36
