traced_probes: lazily initialize FtraceController and make it fail gracefully

This CL:
- Moves the initialization of FtraceController to the first
  CreateDataSourceInstance(). There is no reason why we should
  scan the ftrace folder at startup.
- Makes failures of FtraceController::Create() non fatal. It turns out
  they happen right now on user builds because of SELinux.
