[PATCH v2 1/3] debianize: make changelog date reproducible

[Henning Schild <henning.schild@siemens.com>]

Deriving the date from the filesystem and git also does not always
produce the same result.

In case there is a changelog file and our version does not yet exist
in it, make the new entry 42s later. If there was no changelog use
"1970-01-01 00:00:00 UTC".
