This is a small tweak to try to reduce the travis-ci noise

today, we get errors like:

running install

    raise Exception(msg)
Exception: The libiio library could not be found.
            libiio needs to be installed first before the python bindings.
            The latest release can be found on GitHub:
            https://github.com/analogdevicesinc/libiio/releases

Since the libiio isn't installed or on path during the make package
step. This commit does that.
