Kir Kolyshkin 813cb3eb94 cgroupv2: fix fs2 cgroup init ...

fs2 cgroup driver was not working because it did not enable controllers
while creating cgroup directory; instead it was merely doing MkdirAll()
and gathered the list of available controllers in NewManager().

Also, cgroup should be created in Apply(), not while creating a new
manager instance.

To fix:

1. Move the createCgroupsv2Path function from systemd driver to fs2 driver,
   renaming it to CreateCgroupPath. Use in Apply() from both fs2 and
   systemd drivers.

2. Delay available controllers map initialization to until it is needed.

With this patch:
 - NewManager() only performs minimal initialization (initializin
   m.dirPath, if not provided);
 - Apply() properly creates cgroup path, enabling the controllers;
 - m.controllers is initialized lazily on demand.
