The tests have been introduced inca7be7dc6dand checked for `ecc` in `/proc/self/status` since its creation. We got a new field `Seccomp_filters:` with the Linux commitc818c03b66, means that `ecc` would now match both and interfere with possible test results depending on the host. The field `Seccomp:` got introduced in2f4b3bf6b2and has never changed since then, means we can use it directly to make the tests more strict.
