perf evsel: Fix ftrace:function event recording

Following patch fails (-EINVAL) ftrace:function with enabled user
space callchains:
  cfa77bc4af2c perf: Disallow user-space callchains for function trace events

We need to follow in perf tool itself and explicitly set the
perf_event_attr::exclude_callchain_user flag for ftrace:function
event.
