Commit 6df37c9 bumped the version of
evtest but failed to update the hash.  As a result, hosts which
already have evtest-1.33 source present will build the old version but
label it as evtest-1.34.  Hosts which lack the older source code will
fail their builds.  This commit corrects the issue.

We should think about a way to get Hydra to catch issues like this.
Maybe require that if two FODs have different hashes then they must
have different `${pname}-${version}`s?  Only for FODs, of course.
