From: KP Singh <kpsingh@google.com>
LSM and tracing programs share their helpers with bpf_tracing_func_proto which is only defined (in bpf_trace.c) when BPF_EVENTS is enabled.
Instead of adding __weak symbol, make BPF_LSM depend on BPF_EVENTS so that both tracing and LSM programs can actually share helpers.
