[ansible] Use collectd_config for virt and rdt

Only one of virt and intel_rdt can be enabled at a time, and the
existing checks are based on the existance of a {rdt,virt}.conf file to
determine whether the other plugin is enabled.
This check needed updating, and is now based on whether the other plugin
is in the collectd_plugins value.
