Hi,

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

This is because the testsuite generates a test-mill.log file, which means
that if the tests are skipped (eg. via nochekc), then the package contents
will differ and will therefore be unreproducible.

Patch attached.
