[oe] [meta-oe] [PATCH] libiio: fix build of python bindins

[Neil Armstrong]

In the actual form, the python bindings are never built since the
recipe does not depend on python, thus he cmake script does not
detect python and does not build the bindings.

Add a summy PACKAGECONFIG for the python bindings to make it simpler
to disable.
