Constrain wheel package versions

The presence of IPA packages on PyPI revealed an interesting issue with
make wheel_bundle. pip gives final releases a higher precedence than our
development packages. make wheel_bundle downloads ipa 4.5.0 from PyPI
instead of using our own wheels.

Use a constraint file to enforce correct versions.
