perf bpf: Ignore deprecation warning when using libbpf's btf__get_from_id()
Perf code re-implements libbpf's btf__load_from_kernel_by_id() API as a weak function, presumably to dynamically link against old version of libbpf shared library. Unfortunately this causes compilation warning when perf is compiled against libbpf v0.6+. For now, just ignore deprecation warning, but there might be a better solution, depending on perf's needs.
