Update git submodules

* Update platform/cts from branch 'master'
  to 047094e0f07b80251fa9d35234e184b45e0db6cc
  - Merge "Add myself and David to Keystore CTS owners"
  - Add myself and David to Keystore CTS owners
    
    Update the Keystore CTS owners file:
    * Add David
    * Add myself.
    
    This will remove the dependency on US-based reviewers for all Keystore
    CTS CLs.
    Non-trivial CLs, CLs that are not strictly in the Java layer, or both,
    would still be sent to the right US-based reviewer.
