[tz] zic tweak to warn about non-ASCII in filenames

In my tests, adding a new Zone line for "America/./New_York" at the end of
northamerica, for example, causes the second definition of America/New_York
to silently overwrite the first.  Disallowing "." alongside ".."
effectively requires that all paths be explicit, which allows the
"duplicate zone name" error to handle the rest.
