Bug#1137336: xpenguins: please make the build reproducible

Hi,

Whilst working on the Reproducible Builds effort [0], we noticed that
xpenguins could not be built reproducibly.

This is because the manual package is generated with the current date.
I've attached a patch that seeds this date from SOURCE_DATE_EPOCH, if
available.
