tools: bpftool: Cleanup license mess
Precise and non-ambiguous license information is important. The recent relicensing of the bpftools introduced a license conflict. The files have now: SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause and * This program is free software; you can redistribute it and/or * modify it under the terms of the GNU General Public License * as published by the Free Software Foundation; either version * 2 of the License, or (at your option) any later version Amazingly about 20 people acked that change and neither they nor the committer noticed. Oh well. Digging deeper: The files were imported from the iproute2 repository with the GPL V2 or later boiler plate text in commit b66e907cfee2 ("tools: bpftool: copy JSON writer from iproute2 repository") Looking at the iproute2 repository at git://git.kernel.org/pub/scm/network/iproute2/iproute2.git the following commit is the equivivalent: commit d9d8c839 ("json_writer: add SPDX Identifier (GPL-2/BSD-2)") That commit explicitly removes the boiler plate and relicenses the code uner GPL-2.0-only and BSD-2-Clause. As Steven wrote the original code and also the relicensing commit, it's assumed that the relicensing was intended to do exaclty that. Just the kernel side update failed to remove the boiler plate. Do so now.
