Add some missing glue logic to teach bpf about bare tracepoints - tracepoints without any trace event associated with them. Bare tracepoints are declare with DECLARE_TRACE(). Full tracepoints are declare with TRACE_EVENT(). BPF can attach to these tracepoints as RAW_TRACEPOINT() only as there's no events in tracefs created with them.
