Bug description:
  See also https://discuss.linuxcontainers.org/t/limits-kernel-memlock-
  cannot-exceed-16777216/4856/5

  In containers, the limits.kernel.memlock cannot exceed 16777216 when
  the container is bionic. The memlock setting is set to 16M in systemd
  and cannot be bumped up in an unprivileged container.

  This is fixed in upstream systemd.

  Container ubuntu version:
  Distributor ID:	Ubuntu
  Description:	Ubuntu 18.04.2 LTS
  Release:	18.04
  Codename:	bionic

  systemd package version: 237-3ubuntu10.21
