Check DCH_MAX_ITEM_SIZ limits with <=, not <.

Check DCH_MAX_ITEM_SIZ limits with <=, not <.

We reserve space for the full amount, not one less. The affected checks
deal with localized month and day names. Today's DCH_MAX_ITEM_SIZ value
would suffice for a 60-byte day name, while the longest known is the
49-byte mn_CN.utf-8 word for "Saturday." Thus, the upshot of this
change is merely to avoid misdirecting future readers of the code; users
are not expected to see errors either way.
