Emil Tsalapatis ae0a457f5d bpf: Make perf_event_read_output accessible in all program types. ...

The perf_event_read_event_output helper is currently only available to
tracing protrams, but is useful for other BPF programs like sched_ext
schedulers. When the helper is available, provide its bpf_func_proto
directly from the bpf base_proto.
