Add pkey_only to the service_find calls in host del and disable

The pkey of services is krbprincipalname. The host plugin passes
this full value to service_del and service_disable if the service
hostname matches the requested host.

This limits the amount of data and post-processing done
when host_del and host_disable call service_find. It also saves
a presence query for keytab in each service found.
