networkd-test: ignore failures of test_route_only_dns* in containers

This test exposes a race condition when running in LXC, see issue #11848
for details. Until that is understood and fixed, skip the test as it's
not a recent regression.

(cherry picked from commit 09b8826ea371e027c76a573a226bfd8f8c5652a2)
