agent: is_in_docker not supports cgroup v2

[uar316025]

agent/kraken/agent/utils.py::is_in_docker relies on /proc/self/cgroup
on containers with cgroup v2 which leads to

OSError: [Errno 99] error while attempting to bind on address ('172.17.0.1', 0): cannot assign requested address 

similar problem with jenkins
