grsecurity: work around #19698

This is a temporary work-around to fix using grsecurity on NixOS with
the new kernelPackages/kernelPatches machinery.

For whatever reason, when `security.grsecurity.enable = true`, the grsec
patch ends up being applied twice, causing the kernel build to fail.

Until the root cause of this is identified, we hack around it by simply
pruning duplicate patches in the grsec kernel builder.

Closes #19698
