clone.2: Note a performance benefit of CLONE_INTO_CGROUP
As noted in email by Christian Brauner:
I forgot to mention that spawning directly into a target
cgroup is also more efficient than moving it after creation.
The specific reason is mentioned in the commit message
[ef2c41cf38a], the write lock of the semaphore need not be
taken in contrast to when it is moved afterwards. That
implementation details is not that interesting but it might
be interesting to know that it provides performance benefits
in general.
