Commit 6df37c9aab 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.
