Update git submodules

* Update docs/submodules/releng-xci from branch 'master'
  - Merge "xci: bootstrap-host: Fetch netmask information from IDF"
  - xci: bootstrap-host: Fetch netmask information from IDF

    The IDF file contains the netmask for every network so we should use
    that information instead of using hardcoded values.
