Subject: [PATCH bpf-next] libbpf: fixed build error for samples/bpf/

From: Björn Töpel <bjorn.topel@...el.com>

Commit 8a138aed4a80 ("bpf: btf: Add BTF support to libbpf") did not
include stdbool.h, so GCC complained when building samples/bpf/.

/home/btopel/src/ext/linux/tools/lib/bpf/bpf.h:105:4: error: unknown type name ‘bool’; did you mean ‘_Bool’?
    bool do_log);
    ^~~~
