Update git submodules

* Update docs/submodules/releng-xci from branch 'master'
  - Merge "xci: xci-deploy.sh: Do not 'tee' ssh output"
  - xci: xci-deploy.sh: Do not 'tee' ssh output

    Using 'tee' to capture 'ssh' command output randomly breaks with the
    following error:

    tee: standard output: Resource temporarily unavailable

    Lets just store the log on the host and copy it back in the end.
