libcgroup: Add flags to the walk_tree handle
Introduce a cgroup_tree_handle structure so that we can track flags for
the walk_tree operation. In a number of cases we would prefer to walk the
tree in postorder as opposed to pre-order which is the current default.
This patch does the addition.
Changes since V1:
1. Added checks for !handle as suggested by Bharata
