[PATCH 29/31] inferior::clear_thread_list always silent

[Pedro Alves <pedro@palves.net>]

Now that the MI mi_thread_exit observer ignores "silent", there's no
difference between inferior::clean_thread_list with silent true or
false.  And for the CLI, clean_thread_list() never printed anything
either.  So we can eliminate the 'silent' parameter.
