Bug#896867: ccextractor: please make the build reproducible

[Chris Lamb]

Source: ccextractor
Version: 0.86+ds1-1
Severity: wishlist

Hi,

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

This is because it includes the current date/time in the build.

Patch attached.
