Subject: [PATCH] perf tools: Fix a typo in BTF tracepoint name
In the BTF, tracepoint definitions have the prefix of "btf_trace_".
The off-cpu profilier needs to check the signature of sched_switch
event using the definition. But there's a typo (s/bpf/btf/) so it
failed always.
Fixes: b36888f71c85 ("perf record: Handle argument change in sched_switch")
