[Devel] [PATCH vz10] selftests: ve_printk: initialize required cgroup parameters

[Aleksei Oladko]

kselftest ve_printk may fail if vzctl is not installed on the host,
as the required cgroup parameters are not initialized.

Initialize the required cgroup parameters during test setup
to make the test self-contained.
