[Debian-med-packaging] Bug#1121068: vt: please make the build reproducible

Source: vt
Version: 0.57721+ds-3
Severity: wishlist

Hi,

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

This was because it ships a different binary package depending
on whether the tests are run or not. Specifically, the testsuite
bumped the modification time for the test/decompose directory
and that change is reflected in the .deb.

A patch is attached that always sets the mtime for this directory to
the value of SOURCE_DATE_EPOCH.
