gdi32: pOS2->xAvgCharWidth can be negative however tmAvgCharWidth needs a positive value

[Aric Stewart]

Windows response appears to not allow the user to install the fonts at 
all.  It reports any of the fonts I have which have negative OS/2 
xAveCharWidth as invalid fonts when I try to install them.

This blocks out a few of the main Mac UI fonts.
