contrib/atf: upgrade to 0.26

This new version gets contrib/atf in line with the published version of
the package up on [GitHub][github].

Please note that this release is a major update: it contains several
bugfixes and feature enhancements. Most were already present in the
FreeBSD src repo, but there were a large number of changes made in
addition to what was already present.
