        [Qt] QtLauncher does not load the same set of fonts as the DRT
        https://bugs.webkit.org/show_bug.cgi?id=34959

        This patch adds the option "-use-test-fonts" to the QtTestBrowser.
        When this option is used the webkit fonts are loaded the same
        as they are in DumpRenderTree.  This option can be used on
        QtTestBrowser and run-launcher.  It can only be used
        on Linux systems with FcInit and is configured as such.

        * QtTestBrowser/main.cpp:
