[Reproducible-builds] Bug#829754: bibclean: please make the build reproducible

Hi!

While working on the "reproducible builds" effort [1], we have noticed
that bibclean could not be built reproducibly.
It embeds the username and hostname into the binary, and a timestamp
into a dvi file.

The attached patch this by stripping non-deterministic data and setting
FORCE_SOURCE_DATE, which tells texlive to override the timestamps in the
dvi file with SOURCE_DATE_EPOCH.

Regards,
 Reiner
