ftrace: show virtual PID
Impact: fix PID output under namespaces
When current namespace is not the global namespace,
pid read from set_ftrace_pid is no correct.
# ~/newpid_namespace_run bash
# echo $$
1
# echo 1 > set_ftrace_pid
# cat set_ftrace_pid
3756
Since we write virtual PID to set_ftrace_pid, we need get
virtual PID when we read it.
