Revert fix for "stack buffer overrun", which was a false alarm.

* localtime.c (time1): Shrink size of 'types' local back down
from TZ_MAX_TIMES to TZ_MAX_TYPES.  The smaller value suffices,
since nseen can grow to at most TZ_MAX_TYPES.  (Thanks to
Arthur David Olson.)
* NEWS: Remove mention of non-fix.
