Bug#1037256: debian-installer: GUI font for Japanese was incorrectly rendered

I've checked with 10pt MotoyaLCedar,VL Gothic and BIZ UDGothic.

* MotoyaLCedar 9pt vs 10pt
  9pt: font typeface seems blurred, so it is a bit ugly.
  10pt: ugly blurred rendering was reduced. it has enough
  readability and visibility as others.

* VL Gothic 10pt
  Compared to MotoyaLCedar 10pt, it might be hard to distinguish
  both of their typeface readability and visibility.

* BIZ UDGothic 10pt
  It gives most neat and clear impression in readability and
  visibility, but it might be extra ordinary quality for D-I.

With tweaking default font size, e.g. 9pt to 10pt, 
readability and visibility might be good enough with MotoyaLCedar in
practical use case.
