Read correct font hinting config on Gnome/Unity
Fixes regression against Qt 4. This tries to recreate the logic
from 5c46d9a4c85abbcc0b5db2bbbafded3efd784cd9 in Qt 4, where we
on Gnome would override the default hint style specified in
FontConfig with Xft.hintstyle settings. This is the configuration
used for changing the hint style in the Gnome Tweak Tool.
