Update git submodules

* Update docs/submodules/releng from branch 'master'
  - Merge "prototypes: xci: configure-localhost: Use 'connection: local'"
  - prototypes: xci: configure-localhost: Use 'connection: local'

    Since we are operating on localhost, there is no need to do that via ssh
    so we use 'connection: local' instead. Moreover, we do not need to
    execute everything as root so we drop the remote user directive.
