Enable nf_tables support in kernel

[assoc]

Based on https://github.com/raspberrypi/linux/pull/3696/commits/3b94c0e13940847daa1a66e01d03f266b53be7cd Compiled it myself, and it appears to work with 5.9-rc2 (it literally crashed with earlier kernels).

One thing to note: I tried to compile the kernel with this configuration since 5.7 and it didn't include required modules into the image. When I installed them manually they simply crashed with segmentation fault until recently (i've got crashes even on 5.9-rc2), but today it finally worked.

Hello @assoc

Thanks for your PR.

Does the crash still exist?

Server ruleset works properly, no crashes. This one doesn't work (missing some module for "th" =transport header)
