libiio: fix installing libiio when python3 bindings are enabled

This patch fixes the following error when libiio is installed when
python3 bindings are enabled:

ERROR: Execution of '.../libiio/0.21+gitAUTOINC+565bf68ecc-r0/temp/run.do_install.2349473' failed with exit code 1:

During handling of the above exception, another exception occurred:

Exception: The libiio library could not be found.
            libiio needs to be installed first before the python bindings.

Some time ago a fix for this issue was already discussed here [1].
However in the same discussion also a second issue was being handled.

A fix for the second issue was merged in 51f98865da0. The first issue
didn't pop up anymore and so a fix was never applied.

Recently however after switching from build machine, I started seeing
the first issue. I suspect due to build caching the first issue didn't
pop up anymore before up until now. With this patch, fixes are now
available for both issues handled in [1].
