hasher-priv should forward SOURCE_DATE_EPOCH environment variable to chrootuid'ed processes.
Alternatively, hasher should forward SOURCE_DATE_EPOCH environment variable to rpmbuild.
I'm going to implement the following change: * when building from pkg.tar, use specfile mtime as SOURCE_DATE_EPOCH; * when building from src.rpm, use buildtime as SOURCE_DATE_EPOCH.
