tinyalsa: new package

[Thomas:
 - remove 'default n', since it's the default
 - add dependency on !BR2_PREFER_STATIC_LIB since the Makefile always
   builds a shared library.
 - move from Audio/video applications to Libraries -> Audio.]

+	  a small library to interface with ALSA in the Linux kernel
+
+	  The aims are:
+
+	  - Provide a basic pcm and mixer API
+	  - If it's not absolutely needed, don't add it to the API
+	  - Avoid supporting complex and unnecessary operations that could be dealt
+	    with at a higher level
