Add Chinese translation for eBPF tutorial on BPF struct_ops

This commit introduces a comprehensive Chinese translation of the eBPF tutorial focused on using BPF struct_ops to extend kernel subsystems. The tutorial covers the challenges of kernel development, the benefits of using BPF struct_ops, and provides detailed examples of implementing a kernel module, BPF program, and user-space loader. The content aims to enhance accessibility for Chinese-speaking developers interested in eBPF and kernel programming.
