Revert r427895. The symlinks to Japanese and Chinese fonts are
provided to normalize the font names into standardized ones, and to
make the users be able to install the actual font files into
the location pointed by them. japanese/font-std and chinese/font-std
will install ones which can be redistributed freely, and one can install
commercial font files instead. To avoid installing big Japanese and
Chinese font files for people who do not need them, this port does not
have explicit runtime dependency on japanese/font-std or chinese/font-std.
