Log:
  libpthread_db: undo the memset size change.
  
  I inadvertedly soubled the size of the memset without noticing the
  start address had changed. The size for the memset in pt_map_thread()
  shouldn't actually match the reallocarray() so undo that part of r317200.
  
  This is a re-commit of r317201 to clarify the log.
