Bug#1121804: fff: please make the build reproducible

Hi,

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

This is because "buildandtest" bumps the mtime of fff.h. A patch is
attached that resets the mtime to a determinstic value (and does so
regardless of whether the tests are run).
