Long ago we adapted to Linux kernel changes which inverted the
behaviour of the conntrack --ctdir setting:

nwfilter: check for inverted ctdir
Linux netfilter at some point (Linux 2.6.39) inverted the meaning of the
'--ctdir reply' and newer netfilter implementations now expect
'--ctdir original' instead and vice-versa.
We check for the kernel version and assume that all Linux kernels with version
2.6.39 have the newer inverted logic.
Any distro backporting the Linux kernel patch that inverts the --ctdir logic
(Linux commit 96120d86f) must also backport this patch for Linux and
adapt the kernel version being tested for.

Given our supported platform targets, we no longer need to
consider a version of Linux before 2.6.39, so can drop
support for the old direction behaviour.
The test suite updates are triggered because that never
probed for the ctdir direction, and so the iptables syntax
generator unconditionally dropped the ctdir args.
