cgroup: implement CFTYPE_NO_PREFIX
When cgroup files are created, cgroup core automatically prepends the
name of the subsystem as prefix. This patch adds CFTYPE_NO_ which
disables the automatic prefix. This is to work around historical
baggages and shouldn't be used for new files.
This will be used to move "cgroup.event_control" from cgroup core to
memcg.
