Bug#1059013: wxmplot: please make the build reproducible

[Chris Lamb]

Source: wxmplot
Version: 0.9.58-1
Severity: wishlist

Hi,

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

This is because it embedded the current build date in the manual
pages. Patch attached that seeds this value from SOURCE_DATE_EPOCH if
available.
