Bug#1150109: js8call: please make the build reproducible

[Chris Lamb]

Source: js8call
Version: 3.0.3+ds-1
Severity: wishlist

Hi,

Whilst working on the Reproducible Builds effort [0], we noticed that
js8call could not be built reproducibly.

This is because it embeds a date based on SOURCE_DATE_EPOCH that varies
based on the build timezone.

A patch is attached that uses the 'UTC' flag to CMake's TIMESTAMP
function/macro.
