reformat cjk iconv tables to be diff-friendly, match tool output

the new version of the code used to generate these tables forces a
newline every 256 entries, whereas at the time these files were
originally generated and committed, it only wrapped them at 80
columns. the new behavior ensures that localized changes to the
tables, if they are ever needed, will produce localized diffs. other
tables including hkscs were already committed in the new format.

binary comparison of the generated object files was performed to
confirm that no spurious changes slipped in.
