Update git submodules

* Update docs/submodules/releng-xci from branch 'master'
  - Merge changes from topic 'split-variable-creation-to-task'

    * changes:
      xci: configure-localhost: Do not check /etc/ssl/certs on SUSE
      xci: xci-deploy.sh: Ensure env_reset is not present

  - xci: configure-localhost: Do not check /etc/ssl/certs on SUSE

    /etc/ssl/certs is a symlink so skip this task on SUSE.

  - xci: xci-deploy.sh: Ensure env_reset is not present

    We are making use of 'sudo -E' to preserve environment variables
    when using 'sudo' so we need to make sure that we don't use env_reset
    in the configuration file.
