Summary

games/kanatest: fix ports compliance

 - change += into = where appropriate

While the Porter's Handbook wants us to place japanese as the first
category, Poudriere wants games to be the first category.  Given that
an unhappy Poudriere leads to a broken port, this was not changed.

Try to follow documentation and refer blanket commits more similarly such as portmgr (blanket) instead of "infrastructure change blanket", you can also just use a single line. Approved by: portmgr (blanket), XXX (mentor) in commit message

Thanks, I will do that when committing. I was unaware of the specific convention required.

CATEGORIES= games japanese seems to be correct.
Kanatest port is located at games and listed on japanese second category.

There is other cases where both ports exists, e.g., editors/jed and japanese/jed and CATEGORIES are set accordingly for both ports.
