Bug description:
  On xenial, ssh-keyscan returns zero indicating success, when the
  command fails.

  root at cp1:~# lsb_release -d
  Description:	Ubuntu 16.04.1 LTS

  root at cp1:~# ssh-keyscan -H -t ssh-rsa bad-host
  getaddrinfo bad-host: Name or service not known
  root at cp1:~# echo $?
  0

  On trusty, the exit status is non-zero as expected.

  root at integration-deployer:/home/ubuntu# lsb_release -d
  Description:	Ubuntu 14.04.5 LTS

  root at integration-deployer:/home/ubuntu# ssh-keyscan -H -t ssh-rsa bad-host
  getaddrinfo bad-host: Name or service not known
  root at integration-deployer:/home/ubuntu# echo $?
  255
