Hi,

Whilst working on the "reproducible builds" effort [0], we noticed that
the gettextize tool generates ChangeLog files and entries which include
the current date, rendering generated builds unreproducible (eg. avahi).
The timestamps are also additionally timezone-specific.

The attached patch modifies gettextize to respect SOURCE_DATE_EPOCH[1]
if available.
