Update setuptools pinning

The Ironic API charm is using a very old version of setuptools
due to an old configuration in the build.lock file. Update
build.lock to use a new version of setuptools, remove an
unnecessary setuptools pin from requirements.in, and
ensure the charm builds with the correct requirements pinning.
This should fix a failure in Ironic API that is blocking
testing for Ironic Conductor.
