Don't set AL.BYTE_OFFSET immediately after calling AL.sourcePlay

The sourcePlay call in NativeAudioSource.play is removed, since
setCurrentTime will always do that itself. Additionally, within
setCurrentTime, sourcePlay was happening before setting the byte
offset for non-streamed sounds.

This appears to fix the problem of sounds playing the first part
multiple times, described here:
