net-dns/opendnssec: add patch to build with gcc 14

Upstream's website appears to be having... issues. I did find a bug
reporting link but it led to a subdomain with broken SSL. Unclear how to
progress further.

The sum totality of the issues is a lot of missing headers. Not only did
this affect both configure checks as well as the installable artifacts,
but it also triggered LTO type mismatch errors when the missing stdlib
headers resulted in fake guessed prototypes that then mismatched libc.
Killing two birds with one stone!

+Subject: [PATCH] include lots of headers to pass the basic c99 sniff test
+
+Including configure checks, which currently emit broken results.
+
+And in one case, include config.h early enough to do something.
