That message comes from write-region, which fortunately provide a way to
silence it:

(defun save-messages-buffer ()
  (with-current-buffer (get-buffer "*Messages*")
    ;; (save-buffer 0) or even just (basic-save-buffer) is too noisy, so
    ;; we lose their functionality (including basic-save-buffer-1 and
    ;; basic-save-buffer-2):
    (when (and buffer-file-name
               (buffer-modified-p))
      (write-region (point-min) (point-max) buffer-file-name
                    nil 'quiet))))
