[Reproducible-builds] Bug#815082: arachne-pnr: please make the build reproducible

Hi,

While working on the "reproducible builds" effort [1], we have noticed that
arachne-pnr could not be built reproducibly.

The attached patch sets the embedded date in the man pages generated by txt2man
to UTC with LC_ALL=C to normalize the locale. Once applied, arachne-pnr can be
built reproducibly in our current experimental framework.

Regards,
