Luca Boccassi d75fe9cb1d samples/bpf: Relicense bpf_insn.h as GPL-2.0-only OR BSD-2-Clause
libbpf and bpftool have been dual-licensed to facilitate inclusion in software
that is not compatible with GPL2-only (ie: Apache2), but the samples are still
GPL2-only.

Given these files are samples, they get naturally copied around. For example,
it is the case for samples/bpf/bpf_insn.h which was copied into the systemd
tree: https://github.com/systemd/systemd/blob/main/src/shared/linux/bpf_insn.h

Some more context on systemd's needs specifically:

  Most of systemd is (L)GPL2-or-later, which means there is no perceived
  incompatibility with Apache2 software and can thus be linked with
  OpenSSL 3.0. But given this GPL2-only header is included this is currently
  not possible. Dual-licensing this header solves this problem for us as we
  are scoping a move to OpenSSL 3.0, see:

  https://lists.freedesktop.org/archives/systemd-devel/2021-September/046882.html

Dual-license this header as GPL-2.0-only OR BSD-2-Clause to follow the same
licensing used by libbpf and bpftool:

  1bc38b8ff6 ("libbpf: relicense libbpf as LGPL-2.1 OR BSD-2-Clause")
  907b223651 ("tools: bpftool: dual license all files")
