Update git submodules

* Update docs/submodules/releng from branch 'master'
  - Merge "jjb: xci: xci-run-functest: Fix functest execution"
  - jjb: xci: xci-run-functest: Fix functest execution

    We need to enter the $HOME/releng-xci/xci directory instead of
    /root/relneg-xci/xci since we are ssh'ing as 'devuser'.
