Don't set up decoder parts for DCPs unless they can be played

(i.e. are not encrypted and not missing assets).  Fixes full audio
buffers on locates with large encrypted DCPs and no KDMs; in these
cases silent audio is created by the fill_audio() at the bottom of
Player::pass() but no video is created by anybody.
