Mike O'Driscoll 021de2e1bc util/linuxfw: fix nil pointer panic in connmark rules without IPv6 (#18946) ...

When IPv6 is unavailable on a system, AddConnmarkSaveRule() and
DelConnmarkSaveRule() would panic with a nil pointer dereference.
Both methods directly iterated over []iptablesInterface{i.ipt4, i.ipt6}
without checking if ipt6 was nil.

Use `getTables()` instead to properly retrieve the available tables
on a given system

Fixes #3310
