Update git submodules

* Update docs/submodules/releng-xci from branch 'master'
  - Merge "xci: install-ansible.sh: Fix distribution detection"
  - xci: install-ansible.sh: Fix distribution detection

    Relying on the installed package manager to detect the distribution
    is not reliable since it's possible to install multiple package managers
    at the same time. As such, lets simply use the information in the
    os-release files.
