bpo-41193: Ignore OSError in readline write_history() (GH-21279) 

The write_history() atexit function of the readline completer now
ignores any OSError to ignore error if the filesystem is read-only,
instead of only ignoring FileNotFoundError and PermissionError.
(cherry picked from commit 0ab917e07e)
