Add Hulios to Security projects

[ghaziwali]

Hi ,
I would like to submit Hulios to the Security section of the awesome-ebpf list.

* **Project Link:** https://github.com/ghaziwali/Hulios
* **Suggested Entry:**

* [Hulios](https://github.com/ghaziwali/Hulios) — An eBPF-powered, zero-leak transparent Tor gateway for Linux that secures outbound network traffic using Cgroup v2 socket hooks and LSM raw socket blockers.

### What does the project do?

Hulios is a transparent Tor gateway daemon written in Rust. It utilizes eBPF programs for two main tasks:
1. Cgroup v2 Socket Hooks: Attaches to the root cgroup to automatically mark (fwmark) and redirect outgoing TCP and DNS traffic into an unprivileged userspace Arti instance without modifying global system routes.
2. LSM Raw Socket Blocker: Uses BPF LSM hooks to reject AF_PACKET raw socket instantiation for non-privileged processes, shutting down a common route for cleartext packet leaks.

It follows strict privilege separation (spins up kernel hooks as root, then drops execution down to nobody within a strict seccomp sandbox).

Thank you for maintaining this list!
