libbpf >1.0.0 defines libbpf_bpf_link_type_str(enum bpf_link_type) in src/libbpf.h, which is included by host-pahole. bpf_link_type is defined in linux/bpf.h, therefore the comment stating that pahole doesn't need bpf.h is no longer valid. The original reason to remove bpf.h has been solved with the previous commit: the linux build will prefer the internal bpf.h over the one in HOST_DIR (or in /usr/include). So we can safely keep bpf.h.
