aplay: add a paragraph for '--samples' ('-s') option to aplay manual

Browse source 
A '--samples' ('-s') option was added so that record/playback process is
terminated after handling the same number of PCM frames as a value of the
option. However this option is not described in aplay manual.

This commit adds a paragraph for the option.
