Update git submodules

* Update docs/submodules/yardstick from branch 'master'
  - Merge "Clean functional tests in "test_cli_scenario""
  - Clean functional tests in "test_cli_scenario"
    
    Changed how "test_cli_scenario" tests check the presence
    of a string.
    
    Fixed "test_scenario_show_Lmbench": logic in [1] was incorrectly
    assigning an string value instead of the result of the "in"
    clause.
