[Buildroot] [git commit branch/2022.08.x] package/libbpf: remove architecture restrictions

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=237fe13a0b0468b597838bf0dc883ec195c470a4
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2022.08.x

Since Buildroot commit 3145adfb69ba ("package/libbpf: needs headers >=
4.13"), libbpf depends on Linux headers >= 4.13. This requirement
renders the explicit list of supported architectures, previously added
in f693354c30bd overly restrictive, as the syscall number for bpf(2)
has been defined since Linux 3.18.

Commit f693354c30bd ("package/libbpf: add
BR2_PACKAGE_LIBBPF_ARCH_SUPPORTS") was introduced to fix a build issue
where a toolchain using very old kernel headers (3.13) failed to build
libbpf for ARM, but these architecture dependencies are no longer
needed due to the bump on the kernel headers version requirement.
