Update git submodules

* Update docs/submodules/integration/packaging from branch 'master'
  to bdcd5d8fd8d489ba150a64f63e90b2cfca926c2d
  - Move unitfiles/ to packaging/packages/

    Both RPM and DEB scripts use the same systemd unit files. Therefore,
    unitfiles/ should be in a common directory location.
