tar: work aruond IBM XL C bug

* src/incremen.c (show_snapshot_field_ranges)
(write_directory_file_entry): Use simpler array size expression,
one that evaluates to the same value.  This works around a compiler
bug with IBM XL C.  Problem reported by Yannick Bergeron in
<http://lists.gnu.org/archive/html/bug-tar/2014-01/msg00009.html>.
