Fix unit test helpers for ansible-core 2.19+

ansible-core 2.19 introduced _ANSIBLE_PROFILE alongside _ANSIBLE_ARGS.
set_module_args() in utils.py and test_baremetal_port_group.py only set
_ANSIBLE_ARGS, causing "No serialization profile was specified" errors.
Set _ANSIBLE_PROFILE to 'legacy' to match the pre-2.19 behavior.
