test/scheduler: Ignore failures while removing dummy cgroups

Browse Source 
Upon removal, there's a small chance that new threads would jump into
these cgroups AFTER we read the list of PIDs to migrate. In such a
case, there may be some processes left preventing us from finally
removing the cgroup. Since we can't fully control that without
continuously reading the list, simply ignore it.

Fixes issue #2298
