[libvirt] PATCH: DOn't use policykit if running non-root

[Daniel P. Berrange]

If the libvirtd daemon is running as non-root (ie a regular user) then
there is no point in defaulting policykit, since only clients of same
user account are able to connect to the UNIX socket anyway. This removes
the pointless login prompt when using qemu:///session.
