The purpose of this test is to check that there are no extra file
descriptors left open after repeated calls to runContainer. In fact,
the first call to runContainer leaves a few file descriptors opened,
and this is by design.
Previously, this test relied on two things:
1. some other tests were run before it (and thus all such opened-once
file descriptors are already opened);
2. explicitly excluding fd opened to /sys/fs/cgroup.
Now, if we run this test separately, it will fail (because of 1 above).
The same may happen if the tests are run in a random order.
To fix this, add a container run before collection the initial fd list,
so those fds that are opened once are included and won't be reported.
