dak/dominate.py: keep binaries for at least 1 day
Don't remove binaries that have been in the archive for less than 1 day.
When multiple version of the same binary are uploaded without a dinstall between them, the older versions are never published to the ftp-master archive. They are only published in the buildd archive. This means they aren't available in shapshot.debian.org either. Some of these binaries show up in buildinfo files of other uploads, making it impossible to reproduce the binaries from those uploads.
This change keeps all binaries around for at least a day, to allow them to be published in the ftp-master archive and show up on snapshot.debian.org.
This does not happen for suites with build queues:
- avoid changing the behavior of dak dominate for (old)stable
- binaries from these suites enter the archive via suites with build queues anyway
