test-bpf: skip test when run inside containers

The test reliably fails inside LXC and Docker when run on a new enough
kernel. It's unclear whether this is a kernel, LXC/Docker or systemd
issue and apparently there is no real interest to get this fixed, so
let's skip this test.
As this also covers Travis CI, there is no need for this additional
check anymore.
