[naoqieus] update play audio file method: modify service name

[kochigami]

I updated naoqi's :play-audio-file method: modified service name.
related PR is ros-naoqi/naoqi_driver#109

I confirmed this with Pepper 2.5.5.5 and ROS kinetic as follows:

roslaunch jsk_pepper_startup jsk_pepper_startup.launch network_interface:=<put your eth0 id>
[another terminal] roscd peppereus
roseus pepper-interface.l
pepper-init t
send *ri* :play-audio-file "/audio_file/M1.mp3"
