[gjs] valgrind: Update ignore pattern

    valgrind: Update ignore pattern
    
    This brings back the ignore pattern for the "memory leak" that is
    actually Cairo's static data. It's better to ignore it than call
    cairo_debug_reset_static_data(), since Cairo can fail assertions and
    crash on exit.
    
    Unreviewed, pushing to get master/gnome-3-28 memcheck-clean again.
