[Buildroot] [git commit] package/libbpf: needs headers >= 4.13

[Arnout Vandecappelle]

commit: https://git.buildroot.net/buildroot/commit/?id=3145adfb69ba5332be802fab17f12694ce85d329
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Since its addition in commit f7b8508e4fe9c96bf679cc5423cc1500b6523e83,
libbpf unconditionally uses TCA_BPF_ID which is only available since
kernel 4.13 and
https://github.com/torvalds/linux/commit/e86283071fb0eed28136adb52997888f4beb202b:

netlink.c: In function '__get_tc_info':
netlink.c:515:11: error: 'TCA_BPF_ID' undeclared (first use in this function); did you mean 'TCA_BPF_FD'?
  515 |  if (!tbb[TCA_BPF_ID])
      |           ^~~~~~~~~~
      |           TCA_BPF_FD
