package/bluez-alsa: allow a samplerate conversion for audio playback

In the case of bluetooth audio thet incoming audio stream will be
coming from bluetooth devices at varying sample rates like (44.1, 48,
96, 192 kHz) and the odds of a sound device matching that samplerate
exactly is a bit slim. So in the case of a bluez audio playback the
system will need to do a samplerate conversion.

Thus when enabling bluez-alsa and the alsa plugins select libsamplerate
to support the shift from the incoming samplerates to an often fix-rated
audio device.
