    libgimpconfig: fix string deserialization for some cases
    
    In gimp_config_deserialize_fundamental(), we can't use
    g_value_set_static_string() because that will in the end pass the
    GScanner's temporary scanner->value.v_string to
    GObject::set_property(), and depending on set_property()'s
    implementation, we might not dup the string (for example objects
    created via gimp_config_type_register() will simply use g_value_copy()
    and end up with a dangling pointer as a string member).
