[ci] fix neutron services in functional job

OVN is now enabled by default as a neutron ml2 backend,
so lets adjust the services enabled to match that
of devstack and avoid validation errors:

lib/neutron_plugins/ovn_agent:ovn_sanity_check:365 :   die 365 'The q-agt/neutron-agt service must be disabled with OVN.'
