python3: fix CROSSPYTHONPATH for cross builds

There are cases where target and host are of the same
type and at such instances the target modules may be
loaded if CROSSPYTHONPATH is not correct. This adds
host library paths so that target modules are not
loaded while cross compiling to avoid illegal instruction
issues.
