hosts: Remove nvr1.p.b as managed system

*nvr1.pyrocufflink.blue* has been migrated to Fedora CoreOS.  As such,
it is no longer managed by Ansible; its configuration is done via
Butane/Ignition.  It is no longer a member of the Active Directory
domain, but it does still run *collectd* and export Prometheus metrics.
