[i18n] Disables TimeZoneData tests

To unblock Chromium rolls into Fuchsia.

Until https://bugs.fuchsia.dev/p/fuchsia/issues/detail?id=45491 is fixed.

The current tests do not reinitialize the internal state of `icu_util` correctly,
leading to spurious test errors.  The fix should be straightforward, but takes
some time.  Disabling these tests will allow the rolls to continue while
we fix the issue in the background.
