Use SOURCE_DATE_EPOCH to set MAKE_STAMP instead of using the current

+Subject: [PATCH] configure.ac: set MAKE_STAMP to SOURCE_DATE_EPOCH
+
+If SOURCE_DATE_EPOCH is set, use it to set MAKE_STAMP instead of the
+current time.
+
+Upstream-Status: Inappropriate [embedded specific]
I think that this patch should at least be sent upstream.
Reproducibility is not "embedded specific".
See https://reproducible-builds.org/
Thanks. I will send it upstream.
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.
