Bug#1092251: kmetronome: please make the build reproducible

[Chris Lamb]

Source: kmetronome
Version: 1.4.1-1
Severity: wishlist

Hi,

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

This is because the manual page varied on the build date. Luckily,
kmetronome has a mechanism to set this, and so we can punch through
SOURCE_DATE_EPOCH's value to CMake within debian/rules (see the
attached patch).
