Subject: [PATCH 1/2] make package build reproducible

Date: 2018-11-01

sometimes our patches touch .man input files
and mdate picks up their mtime for use in man-page headers
so we clamp the mtime to SOURCE_DATE_EPOCH if set
similar to https://www.fabiankeil.de/sourcecode/electrobsd/ElectroBSD-r312620-6cfa243f1516/0079-contrib-groff-mdate.sh-Use-EPOCH_DATE-when-set.diff

upstream commit 677274dafc5dd5f79f2a6d16270b21d2f5a16c5b
rewrote it to similar perl, too
