test: Fix and disable IPSec + bpf_host test
test: Fix and disable IPSec + bpf_host test

We currently have two IPSec tests in native routing mode, one with
bpf_host loaded on the native device and one without. By default,
bpf_host is loaded on native devices if the host firewall or NodePort
are enabled, so the goal of the first test is to verify IPSec still
works in those conditions.

Similarly, in tests, we only define 'devices' if the host firewall or
NodePort are enabled. Devices are therefore undefined on 4.9 by default.
Therefore, on 4.9, the 'with bpf_host' variant of the IPSec test runs
with devices unspecified and doesn't actually test the integration with
bpf_host.

This commit first fixes that by explicitly defining devices in the test.
Unfortunately, the integration with bpf_host is actually broken because
of https://github.com/cilium/cilium/issues/12205, so we have to disable
the test until that issue is fixed.

So basically, this commit is a noop: it fixes a test that wasn't testing
anything new just to then disable it because the tested functionality is
broken  ¯\_(ツ)_/¯
