[tz] [PROPOSED 1/3] Define fullname only if needed

[Paul Eggert via tz]

* localtime.c (union local_storage): Define fullname member only
if needed.  This saves space on unlikely platforms where
sizeof (struct file_analysis) < PATH_MAX, and is closer to FreeBSD.
(tzloadbody): Mention fullname only if declared.
