ironic-inspector: install the dnsmasq subpackage explicitly
ironic-inspector: install the dnsmasq subpackage explicitly

We are splitting the ironic-inspector package into RDO into
ironic-inspector itself and its dnsmasq service. This change
updates kolla to install both packages to avoid breakages when
RDO removes mutual dependency between them.
