Complement commit c579f48edba8 ("Remove cached PID/TID in clone") and 
remove the `match_pid' parameter not used by `iterate_thread_list' any 
longer.  Update call sites accordingly.

	* nptl_db/td_ta_thr_iter.c (iterate_thread_list): Remove 
	`match_pid' parameter.
	(td_ta_thr_iter): Update accordingly.

Hi,

 Discovered while looking into a GDB MIPS/Linux core file handling bug: 
<https://sourceware.org/ml/gdb-patches/2017-11/msg00184.html>.

 No build issues with `i686-linux', `mips-linux' or `x86_64-linux'.  OK to 
apply?

  Maciej
