It is practically impossible to use any of the unzip slave ports. This
is because archivers/unzip is used by the ports infrastruction (via
USES=zip, USES=zip:infozip) and each slave port conflicts with it.
If you install the slave port first, then the port infrastructure can't
install archivers/unzip (although if attempted, the extracts dependency
might be satisfied by the slave port so it might actually work).
In any case, this change:
* Adds "iconv" support as an non-default option
* Add a localization group that can have zero or one selection
* That group contains Chinese, Korean, or Russian support
* WITH_UNZIP_UNREDUCE support was removed (I'm not sure it even worked)
* Makefile was simplified (several loops removed)
* Removes unzip-iconv, Chinese, Korean, Russian slave ports
