libiio: Initial Android.bp build file

This introduces the required build logic to create
in the Android build system.

It adds:
 - a blueprint file;
 - an explicitly generated iio-config.h, as this is ordinarily produced
   via CMake, and this doesn't seem possible to replicate trivially under
 - an include file for exporting.
