gdb: remove prune_threads in thread_db_target::update_thread_list
Pedro mentioned that this prune_threads call in
thread_db_target::update_thread_list was not needed, and it was probably
an oversight to leave it there in the work following commit e8032dde10b
("Push pruning old threads down to the target"). That commit changed
the "find new threads" target operation to "update thread list", making
the target responsible of adding new threads and removing exited
threads, rather than just adding new threads. Commit e8032dde10b moved
the prune_threads calls previously done in common code into each
target's update_thread_list method, in order to keep the existing
behavior, which is why this prune_threads call ended up there.
In the mean time, the linux-nat target was taught to update_thread_list,
and thread_db_target::update_thread_list defers to that for any live
inferior, so the prune_threads call is not needed there. Otherwise, the
thread_db_target::update_thread_list implementation based on
td_ta_thr_iter_p only knows how to add new threads, not how to delete
exited threads, but that is only used for non-live inferiors, where
threads can't exit anyway. So the prune_threads call is not needed for
that case either.
