Title:
  `sudo --login --user USERNAME` throws `setrlimit(RLIMIT_CORE):
  Operation not permitted` error when run inside a container.

Status in sudo package in Ubuntu:
  Confirmed

Bug description:
  When using `sudo --login --user USERNAME` with Ubuntu Focal currently,
  it will correctly operate but it will also throw the following error
  before continuing with the logon process (which completes successfully
  except for the stated error):

  sudo: setrlimit(RLIMIT_CORE): Operation not permitted

  A full run of this was tested in a Focal LXD container after dropping
  to a root shell to reproduce (arstotzka is the host system, focal-test
  is the test container):

  teward at arstotzka:~$ lxc shell focal-test
  root at focal-test:~# sudo --login --user ubuntu
  sudo: setrlimit(RLIMIT_CORE): Operation not permitted
  To run a command as administrator (user "root"), use "sudo <command>".
  See "man sudo_root" for details.

  ubuntu at focal-test:~$
