Freetype: Don't embolden bold fonts

If a font does not set the "bold" flag in its OS/2 table, we check
the weight from the same table to determine whether it is bold or
if we have to embolden it synthetically. But the actual definition of
bold in OS/2 is 700 (which is also what QFont::Bold is documented
to correspond to in qfont.h).

The result was that we would embolden fonts with bold weight if
the bold flag was not set. An example of such a font was the
CJK JP family of Noto Sans.

[ChangeLog][Text] Fixed a problem where certain bold fonts would be
synthetically emboldened by Qt when using the Freetype font engine.
