      Filter out all linked fonts in qfontdatabase_s60.cpp, registerScreenDeviceFont(). That seems to be possible by using CLinkedTypefaceSpecification::FetchLinkedTypefaceSpecificationL and checkiung for KErrNone.

      Reason: Linked fonts add additional cryptic type face names to the QFontDatabase. Also, I suspect them being the reason for issues like QTBUG-19842, because I immagine that the 'cmap' table for a a linked font is not adjusted the linkage, thus is invalid. And according to QT-5098, skipping linked fonts avoids a huge slowdown in application startup.
