Eric W. Biederman 4b1c32bfaa cgroup-v1: Require capabilities to set release_agent 
commit 24f6008564 upstream.

The cgroup release_agent is called with call_usermodehelper.  The function
call_usermodehelper starts the release_agent with a full set fo capabilities.
Therefore require capabilities when setting the release_agaent.
