This package is moving to flit and will soon be dropping distutils
compatibility support.
We need to use flit-bootstrap as opposed to the normal flit setup
type since host-python-pypa-build depends on host-python-installer.
We need to add the src directory to the PYTHONPATH so that installer
can run from the src directory when installing itself.
We need to explicitly add host-python-flit-core to the dependencies -
only host-python-installer is automatically added to the depenedencies
for flit-bootstrap packages, and this would create a circular dependency
so is explicitly excluded in the infra.
