package/libbpf: add BR2_PACKAGE_LIBBPF_ARCH_SUPPORTS

libbpf does not support all architectures, for example ARM is not
supported resulting in the following build failure:

bpf.c:53:4: error: #error __NR_bpf not defined. libbpf does not support your arch.
 #  error __NR_bpf not defined. libbpf does not support your arch.
    ^
