Offline LAN crossplay fixes and correct PS3 tutorial pack source

- Handle pre-login permission checks in offline/system-link mode when
  Xbox Live is disabled (grant canPlay/canPlayLocal/friends permissions)
- Log Offline LAN handshake events (PreLogin/Login/GAME_PLAY state)
- Stub: set QNET_STATE_GAME_PLAY on SetGamePlayState and advertise the
  session joinable when hosting
- PS3 postbuild: source the PS3 tutorial pack from the PS3 tree instead
  of the PSVita tree so the big-endian PS3 DLC parser doesn't read a
  little-endian pack as garbage (fixes RPCS3 boot crash in
  DLCManager::processDLCDataFile)
