Makefile: add explicit connection for inventory generation

Add --connection=local and --inventory localhost, to the inventory
generation target since we're generating the hosts file and don't
have a proper inventory available yet.

This avoids inventory parsing warnings by being explicit about
the execution context, following the same pattern as ansible.cfg
generation.
