Subject: [PATCH] feat: set SOURCE_DATE_EPOCH on chunkah (#2651)

Should help with reproducibility and might make updates smaller for
unpackaged contents like wallpapers, homebrew.

Only downside so far that I see is that `podman images` and the like
will show up at the bottom with 56 years ago and so on. Labels like
`org.opencontainers.image.created` are of course not affected by this.
