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.
