    giscanner: Fix pointer parsing.
    
    They were parsed in wrong order resulting in having wrong pointer
    being const. For example - g_settings_list_schemas return type is
    normally 'const gchar *const *', but parsing result was
    'const gchar ** const'.
    
    This was unnoticed, because pointer constness information is rather
    not used by gobject-introspection now.
