Subject: [RFC PATCH v2 0/1] bpftool: Align dumped file headers with skeletons

Hi.

First, I hope you are fine and the same for your relatives.

In this patch, I aligned dumped C file headers with that of skeletons, so the
first lines of C dumped files are the following:
/* SPDX-License-Identifier: (LGPL-2.1 OR BSD-2-Clause) */
/* THIS FILE IS AUTOGENERATED BY BPFTOOL! */
#ifndef __VMLINUX_H__
#define __VMLINUX_H__

The goal is to warn users this file must not be edited as it was automatically
generated.
Indeed, skeletons also contain the same message.

This patch is clearly not a big change which impacts the future of bpftool but
I think it could be welcomed.
If you see any way to improve it or have any question, feel free to ask.

Change since:
 v1:
  * Drop command used to generate the file and use the same warning message
  as skeletons.
  * Add SPDX license.
