Andrea Righi 7ff06a6ff0 scx_rustland: prevent misaligned pointer dereference 
The buffer used to store struct queued_task_ctx items fetched from the
BPF ring buffer needs to be aligned to the architecture register size,
otherwise we may hit misaligned pointer dereference issues, such as:

  thread 'main' panicked at src/bpf.rs:162:43:
  misaligned pointer dereference: address must be a multiple of 0x8 but is 0x56516a51e004
  note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Prevent this by making sure the buffer is always aligned to 64-bits.

RUST SCHEDULERS

Introduction

This directory contains schedulers with user space rust components.

The README in each scheduler directory provides some background and describes the types of workloads or scenarios they're designed to accommodate. For more details on any of these schedulers, please see the header comment in their main.rs or *.bpf.c files.
