[meta-tensorflow,3/3] tensorflow-lite: add recipe

Adding 2.6.1 tensorflow-lite recipe.
This recipe is directly based on the corresponding 2.6.1 tensorflow
recipe.

It has been build tested with latest honister and tested on
several mediatek soc using benchmark_model and label_image (C++ and
python)
