samples/bpf: fix bpf_perf_event_output prototype

The commit 555c8a8 ("bpf: avoid stack copy and use skb ctx for event output") started using 20 of initially reserved upper 32-bits of 'flags' argument in bpf_perf_event_output(). Adjust corresponding prototype in samples/bpf/bpf_helpers.h Signed-off-by: Adam Barth <[email protected]> Signed-off-by: Alexei Starovoitov <[email protected]> Acked-by: Daniel Borkmann <[email protected]> Signed-off-by: David S.
