build: Allow to override build date with SOURCE_DATE_EPOCH
and make host and user overridable
in order to make builds reproducible.
See https://reproducible-builds.org/ for why this is good
and https://reproducible-builds.org/specs/source-date-epoch/
for the definition of this variable.
Also switch to UTC to be independent of timezone.
Also use ISO 8601 date format to be easier to parse.
This is similar to c9f40227836b827b71a6cbc4744d4b7151b2fcef
and df82ec8fe7d91467c8b479bba74c761c0a6ffc59
which was lost in the move away from automake.
Note: This date call is designed to work with different flavors
of date (GNU, BSD and others).
If only GNU (Linux) support is needed, the patch can be simplified.
This PR was done while working on reproducible builds for openSUSE.
Type: fix
