kola/tests/docker: Skip no-new-privileges test for Docker 1.12

[pothos]

Recently two Docker parameter test cases were added:

1. --security-opt=label=disable --security-opt=no-new-privileges
2. --security-opt=no-new-privileges
   As the second case causes a Docker 1.12 runc panic in our current
   setup, skip this test when Docker 1.12 is detected.

How to use/test

$ make
$ make test
$ cd bin
$ ./kola run --board=amd64-usr --aws-ami=ami-0c7295725fccdee9b --aws-region=us-west-2 --aws-type=t3.small --aws-iam-profile=jenkins-test --platform=aws --channel=beta --torcx-manifest=torcx_manifest.json --aws-credentials-file ~/.aws/credentials-kola docker.torcx-manifest-pkgs
