[Fontconfig] Why is the default weight FC_WEIGHT_MEDIUM?

[Akira TAGOH]

Hi,

That sounds reasonable to me so that the normal weight is also default in CSS.
Does anyone else have any objection about this change? one concern is
if there are anyone who are relying on current behavior, this change
will breaks it despite you get a fix.
