[Buildroot] [PATCH 2/4] package/libbpf: remove architecture restrictions

[Tobias Waldekranz]

Since 3145adfb69ba, 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.

f693354c30bd was introduced to fix a build issue where a toolchain
using very old kernel headers (3.13) failed to build libbpf for ARM.
