More PR13083 fixes to avoid sleeping in the task_finder.

* runtime/task_finder.c (__stp_get_mm_path): Call down_read_trylock()
  instead of down_read() to avoid the possibility of sleeping.
  (stap_start_task_finder): Call task_lock() to make sure a task's mm
  doesn't go away while we're looking at it.
