Subject: disable the cgroups release agent when shutting down
During shutdown, when we try to clean up all remaining processes, the
kernel will fork new agents every time a cgroup runs empty. These
new processes cause delays in the final SIGTERM, SIGKILL logic.
Apart from that, this should also avoid that the kernel-forked binaries
cause unpredictably timed access to the filesystem which we might need to
unmount.

Subject: cgroups-agent: remove ancient fallback code; turn connection error into warning
During re-execution and shutdown cgroups agents might not be able
to connect to systemd's private D-Bus socket, the printed error to
the console is misleding in that case, so turn it into a warning.
