ensure-pip: use dummy package for testing

This currently uses zuul-client to test installation.  Unfortunately
for the testing the recent release dropped support for older pythons
we still need to test with.

To avoid this, make a dummy package that we include in zuul-jobs that
does nothing, but will also install anywhere.
