Bug#882818: fswatch: please make the build reproducible

[Chris Lamb]

Source: fswatch
Version: 1.11.2+repack-2
Severity: wishlist

Hi,

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

This is because the manpage used the output of the date(1) cmd

Patch attached.
