[PATCH bpf-next v3 2/8] libbpf: Mark libbpf_kallsyms_parse static function

[Yonghong Song <yonghong.song@linux.dev>]

Currently libbpf_kallsyms_parse() function is declared as a global
function but actually it is not a API and there is no external
users in bpftool/bpf-selftests. So let us mark the function as
static.
