fix: linux firewall improvements

- Add xargs -r to avoid spurious delete when no duplicate chain entries exist
- Pre-register routing table name in /etc/iproute2/rt_tables
- Mount legacy net_cls cgroup v1 on cgroup v2 (unified hierarchy) systems
- Add 400.allowPIA anchor during install
- Ignore errors on ip route flush for table that may not exist yet
- Remove rt_tables entry on teardown
