Subject: cgtop: recursively count cgroup member tasks

When showing the number of tasks in a cgroup, recursively count tasks in
child cgroups and include them in the number. This ensures that the
number of tasks is cummulative the same way as memory, cpu and IO
resources are.

Old behaviour can be restored by passing the new --recursive=no switch.
