Bernd Kuhls 513f800cf3 package/libbpf: fix bpftrace build with kernel headers 6.0 ...

Buildroot commit 97e2f63bdf bumped
bpftrace from 0.23.3 to 0.24.2.

This release includes upstream commit
7578314df6
which was added to version 0.24.0 and makes use of
bpf_iter_link_info.task that was added to the linux kernel in version
6.1:
f0d74c4da1

causing build errors when the toolchain contains kernel headers version
6.0 because the libbpf package does not update their headers:

output/build/bpftrace-0.24.2/src/attached_probe.cpp: In static member
 function 'static bpftrace::Result<std::unique_ptr<bpftrace::AttachedIterProbe> >
 bpftrace::AttachedIterProbe::make(bpftrace::Probe&,
 const bpftrace::BpfProgram&, std::optional<int>)':
output/build/bpftrace-0.24.2/src/attached_probe.cpp:1437:11: error:
 'union bpf_iter_link_info' has no member named 'task'
 1437 |     linfo.task.pid = *pid;

The build error can be reproduced with this defconfig

BR2_aarch64=y
BR2_KERNEL_HEADERS_VERSION=y
BR2_DEFAULT_KERNEL_VERSION="6.0.19"
BR2_PACKAGE_HOST_LINUX_HEADERS_CUSTOM_6_0=y
BR2_TOOLCHAIN_BUILDROOT_CXX=y
BR2_PER_PACKAGE_DIRECTORIES=y
BR2_PACKAGE_BPFTRACE=y

on the 2026.02.x branch as of 0be927b89a.
