net-dns/djbdns: new EAPI=8 revision with fixed parallel build.
The parallel build fix comes via an updated ipv6 patch, courtesy of
Felix von Leitner. (Thanks for the fast response!)
This also includes the ever-dangerous manual rebasing of two CVE patches
on top of the new ipv6 patch, made scarier by the fact that I don't
actually ipv6 myself. Fortunately those patches are not too crazy.
Closes: https://bugs.gentoo.org/881349
