I left a few out where writing it explicitly was better
for various reasons.

Andrew Dunham 6927a844b1 util/linuxfw: add build constraints excluding GOARCH=arm
This isn't currently supported due to missing support in upstream
dependencies, and also we don't use this package anywhere right now.
Just conditionally skip this for now.

Fixes #7268

Andrew Dunham ba48ec5e39 util/linuxfw: initial implementation of package
This package is an initial implementation of something that can read
netfilter and iptables rules from the Linux kernel without needing to
shell out to an external utility; it speaks directly to the kernel using
syscalls and parses the data returned.

Currently this is read-only since it only knows how to parse a subset of
the available data.
