[Rpm-maint] [rpm-software-management/rpm] Allow SOURCE_DATE_EPOCH to override file timestamps (#144)

Limit the maximum date to SOURCE_DATE_EPOCH, if defined
similar to the tar --clamp-mtime option

based on a patch by Nicolas Vigier <boklm at torproject.org>

together with previously merged
b8a54d6a1e9bb6140b6b47e23dc707e4b967537e from @boklm

This allows rpmbuild to produce bit-by-bit identical rpms on different hosts when setting rpmmacros to
%_buildhost reproducible
%source_date_epoch_from_changelog Y
%clamp_mtime_to_source_date_epoch Y

macro is needed, because not everyone might want it, as it is known to affect python packages that include .pyc files which reference the original timestamp. Those will still work but re-compile on demand.
