The legacy cgroup hierarchy does not support reliable empty notifications in containers and if there are left-over subgroups in a cgroup. This makes it hard to correctly wait for them running empty, and thus we previously disabled this logic entirely. With this change we explicitly check for the container case, and whether the unit is a "delegation" unit (i.e. one where programs may create their own subgroups). If we are neither in a container, nor operating on a delegation unit cgroup empty notifications become reliable and thus we start waiting for the empty notifications again. This doesn't really fix the general problem around cgroup notifications but reduces the effect around it. (This also reorders #include lines by their focus, as suggsted in CODING_STYLE. We have to add "virt.h", so let's do that at the right place.) Also see #317.
