Use SOURCE_DATE_EPOCH to set MAKE_STAMP instead of using the current
time, thereby improving reproducibility.

I think that this patch should at least be sent upstream.
Reproducibility is not "embedded specific".

I have checked upstream and found that this commit[1] in development
branch has already resolved the reproducibility issue. However, since
the changes involve multiple patches, backporting them is not appropriate.
Therefore, I think we can keep the current Upstream-Status in the patch.
It will be dropped upon the next release of nftables.

Awesome news :)
In that case, your patch could be seen as the "Upstream-Status: Backport" of this URL...
At least, please add the URL to the patch as a reference so this
precious information is not lost when the upgrade will happen.
Thanks!
