This specifically fixes % man -P ktrans We dont have font widths for kanji in our troff font files, so we can use aux/mnihongo to render the character using libdraw, and grab the bitmap from there. It's not pretty, but aux/mnihongo exists so lets at least use it. This also updates /sys/man/1/ktrans to specify the Jp font to comply with aux/mnihongo.
