Nice.  Thanks for pointing this out!  That explains why I couldn't fix
the problem by fussing with the following .strftime() call.

Verilator upstream source has moved on, with help from Vagrant and me,
to (mostly) ignore the time-of-build, using instead the in-built
release date or a timestamp from git.  See commit bc6a7787.

Since I didn't get reproducibility right on my first attempt, could
someone with access to r-b infrastructure check if the aforementioned
patch _actually_ results in reproducible verilator Debian packages?
If so, I can turn in a proper Debian bug report.
