Cole Robinson 756e6ab467 Allow polkit auth for VNC and SSH users
If you are sitting in front of a physical machine and logged in as
a regular user, you can connect to the system libvirtd instance
by providing a root password to policykit. This is how most
virt-manager users talk to libvirt.

However, if you are launching virt-manager over ssh -X, or over
VNC started from say /etc/sysconfig/vncservers, our policykit policy
rejects the user outright, providing no option to provide the root
password. This is confusing to users and doesn't seem to serve much
point.

Change the policy to allow inactive (VNC) and non-local (SSH, VNC)
to provide root credentials for accessing system libvirtd. We use
auth_admin rather than auth_admin_keep so that credentials aren't
cached at all, and every subsequent reconnection to libvirt requires
auth.
