net: Add dummy nft_reject_ipv[46].ko files

This is a dummy file to please the OpenWrt build system which no longer supports 4.19. Until we have found a better solution, this hack will please the OpenWrt build system. Since the kernel or the modules compiled from this repo never end up in the image that ends up on the device, the effort spent on maintaining the package dependency hierarchy for 4.19 in the OpenWrt build system is futile. If we ever go for a full integration (with its own downsides in terms of maintenance cost), then we have to maintain our own 4.19-based kernel-packages.

I am everything but proud of this.... .... but given that those files are not even used, it seems pointless to add many ifs in the Makefile to support 4.19. It is probably 1-2 weeks to add support for kernel 4.19 to the Makefiles, I guess.

I agree that's the best compromise.

Not sure whether this is really the best way, but let's go for it until we have found a better one. I will create a ticket about it. There are more modules with failures, so for instance activating firewall4 will create more errors, so we might need to find some solution.

One approach, I thought about is to keep a separate config of the kernel package definitions that are 4.19-compatible. Maybe that is easier than maintaining something like if IPV6&&!KERNEL_4_19 for invididual kmod modules, their config options, resulting ko-files and dependencies.
