Remove usage of find_inferior in last_thread_of_process_p

Browse Source 
Replace it with find_thread.  I also modified the code a bit to use a
lambda and a boolean.

gdb/gdbserver/ChangeLog:

	* linux-low.c (struct counter): Remove.
	(second_thread_of_pid_p): Remove.
	(last_thread_of_process_p): Use find_thread.
