More fix for live 

- Neither live with or without key rotation did not output the right
  result.
- No key rotation: did not produce any ContentProtection element.
- With key rotation: did not have DRM specific ContentProtection.
- To get key rotation working with shaka player, <cenc:pssh> elements
  are removed.
