[PATCH net 2/4] selftests/tc-testing: Fix Error: failed to find target LOG

[Vlad Buslov <vladbu@nvidia.com>]

Add missing netfilter config dependency.

Fixes following example error when running tests via tdc.sh for all XT
tests:

 # $ sudo ./tdc.py -d eth2 -e 2029
 # Test 2029: Add xt action with log-prefix
 # exit: 255

 # bad action parsing
 # parse_action: bad value (7:xt)!
 # Illegal "action"
 #
 # -----> teardown stage *** Could not execute: "$TC actions flush action xt"
 #
 # -----> teardown stage *** Error message: "Error: Cannot flush unknown TC action.
