Fix _kill_process AttributeError when _stats_logger is unset (#6417)
* Fix _kill_process AttributeError when _stats_logger is unset

LlamaCppBackend._kill_process references self._stats_logger in its finally
block, but __init__ only sets self._stats_logger = None partway through. If
__init__ raises before that line, or the backend is built via __new__ (as the
kill-path unit test does), teardown crashes with AttributeError instead of
cleaning up the process.

Guard the reference with getattr, matching the existing
hasattr(self, '_chat_template_file') guard in the same finally block. Fixes
test_kill_process_records_timestamp_on_actual_kill.

* Also guard _stdout_thread in _kill_process teardown

Review follow-up: the same finally block also reads self._stdout_thread, which
is unset on a partially-built / __new__ backend. Guard it with getattr like
_llama_log_fh below, and add a test that _kill_process tolerates a backend with
those optional attrs unset. Trim the _stats_logger comment.
