kselftest rtnetlink.sh test case failure is not a regression on 4.16,
4.14, 4.9 and 4.4 builds.
Because it used to skip due to missing tc tool.

Now the ''tc' tool added to Open Embedded build and test running and
reported failed.
This is not a regression in the kernel.
It is a change in the user space.

Old output
============
SKIP: Could not run test without the tc tool
selftests: rtnetlink.sh [PASS]
https://lkft.validation.linaro.org/scheduler/job/225015#L2255


New output
=============
RTNETLINK answers: Operation not supported
Cannot find device \"test-dummy0\"
FAIL: cannot add dummy interface
selftests: rtnetlink.sh [FAIL]
https://lkft.validation.linaro.org/scheduler/job/226352#L3375
