    Hurd: In the CLI, use parse_thread_id instead of global_thread_id_to_ptid
    
    Follow-up to commit 14f6890677849172a4b13779acd9089c9baa3a81.
    global_thread_id_to_ptid expects global thread numbers, which are nowadays only
    used in MI, never presented to the user in the CLI.  Since this is a CLI
    command, it should accept the inferior-qualified format instead.
    
    	gdb/
    	* gnu-nat.c (set_sig_thread_cmd): Use parse_thread_id instead of
    	global_thread_id_to_ptid.
