We've hit this problem at least twice in the past, last time with the new
Vector skin update. With this change it should not be necessary to do
anything manually after an update.

- When loki hits 5.5G RSS, aggressively reclaim its memory. This puts
  it under memory pressure.
- When loki hits 6G RSS, invoke the kernel OOM killer.
- When loki is under severe memory pressure, have systemd-oomd kill it.

- Allow killing of any cgroup if swap is about to run out. When swap is
  at least 90% full, oomd will kill a cgroup, tending to kill the cgroup
  with the highest swap usage.
- Allow killing cgroups of logged in users under severe memory pressure.
  When a cgroup is stalled waiting for memory at least 60% of the time,
  for at least 30 seconds, oomd will attempt to kill it or one of its
  descendant cgroups.

This partially reverts commit c3d00264.

The smartd changes are not ready to land yet and were included in the
above commit by accident.
