Current working directory is a process level resource. We cannot call
chdir in parallel from multiple threads, which would cause cwd confusion
and result in UT failures.
The agent code itself is correct that chdir is only called from spawned
child init process. Well, there is one exception that it is also called
in do_create_container() but it is safe to assume that containers are
never created in parallel (at least for now).

Use conditional compilation (#[cfg]) to change chroot behaviour
at compilation time. For example, such function will just return
`Ok(())` when the unit tests are being compiled, otherwise real
chroot operation is performed.
