pcm: introduce defaults.pcm.compat to change the params choose behaviour

Browse source 
Having getenv directly in the function is not a good idea. Allow
configuration of the behaviour change in snd_pcm_param_choose() function
using alsa.conf. Use the environment variable LIBASOUND_COMPAT only
as fallback.
