This is a toolchain issue that potentially affects hundreds of packages
and should IMO be fixed centrally, at least for those packages that use
these debhelper short form dh rules.
The reason only a handful show up in the current reproducible.debian.net
CI setup is that it only triggers when the two builds happen on different
sides of midnight UTC. Once we start testing builds on different dates,
I expect the number of those to explode.
