Namhyung Kim 177f4eac7f perf ftrace: Add -b/--use-bpf option for latency subcommand 
The -b/--use-bpf option is to use BPF to get latency info of kernel
functions.  It'd have better performance impact and I observed that
latency of same function is smaller than before when using BPF.

Committer testing:

  # strace -e bpf perf ftrace latency -b -T __handle_mm_fault -a sleep 1
