Subject: [PATCH] nixos/ananicy: re enable BPF on hardened kernels

This was a workaround to begin with, as hardened kernel didn't support tracing.
Back then kernel level tracing was only available through debugfs, and now that
tracefs has been available on NixOS for a while now, enabled in
Link: https://github.com/NixOS/nixpkgs/pull/388751

This workaround can be removed and bpf can be used with tracefs.
