Jordan Rome ffc7b7dc4a Fetch and build bpftool by default 
This pairs with the new default behavior to fetch and build libbpf
and is mostly being used so we can use the latest bpftool and libbpf.

scx_rlfifo

This is a single user-defined scheduler used within sched_ext, which is a Linux kernel feature which enables implementing kernel thread schedulers in BPF and dynamically loading them. Read more about sched_ext.

Overview

scx_rlfifo is a simple FIFO scheduler runs in user-space, based on the scx_rustland_core framework.

Typical Use Case

This scheduler is provided as a simple template that can be used as a baseline to test more complex scheduling policies.

Production Ready?

Definitely not. Using this scheduler in a production environment is not recommended, unless there are specific requirements that necessitate a basic FIFO scheduling approach. Even then, it's still recommended to use the kernel's SCHED_FIFO real-time class.
