Update git submodules

* Update docs/submodules/releng-xci from branch 'master'
  - Merge "xci: files: install-lib.sh: Install pip packages as user"
  - xci: files: install-lib.sh: Install pip packages as user

    We can avoid "polluting" the system with all the pip packages we install
    so we could just install them in the user's home directory.
