Hi,

Whilst working on the Reproducible Builds effort [0], we noticed that
golang-github-kshedden-dstream could not be built reproducibly.

This is because the testsuite does not clean up a number of files it
generates, so that if the tests are skipped (via nocheck), then the
binary package will differ.

A patch is attached that removes these files.
