 6. Check if the `pid_target` variable is equal to the current process's PID. If `pid_target` is not 0 and is not equal to the current process's PID, return `false` to skip capturing the `sys_openat` call of that process.
 7. Use the `bpf_printk()` function to print the captured process ID and relevant information about the `sys_openat` call. These information can be viewed in user space using BPF tools.
 8. Set the program license to "GPL", which is a necessary condition for running eBPF programs.### Instructions
