dev-java/openjdk: add 8.402_p06

* Fix various modern C issues - all by backporting parts of later JDK 11/17/21 patches.
* cgroup2 issues: Assuming bug #926247 affects the source build too, but not
  verified, so tagging that.
* Drop stale -fcommon workaround (bug #850505).
* Build with -std=gnu++14 because of -Wregister for Clang 17+ compat (bug #918655).
  (Part of the build uses -std=gnu++98 but not all of it.)
