docs: use JavaScript based PolicyKit .rules files

Browse Source 
PolicyKit authentication rules have switched to a JavaScript based
format quite some time ago. See:

http://davidz25.blogspot.com/2012/06/authorization-rules-in-polkit.html

While backwards compat for the old .pkla format is still available, it
makes sense to point people first at the new format.

The SSHPolicyKitSetup wiki page seems pretty stale, so remove the
reference to it.

The default policy can be overridden by creating a new policy file in the
local override directory <code>/etc/polkit-1/localauthority/50-local.d/</code>.
Policy files should have a unique name ending with .pkla. Using reverse DNS
naming works well. Information on the options available can be found by
reading the pklocalauthority man page. The two libvirt daemon actions
available are named <code>org.libvirt.unix.manage</code> for full management
access, and <code>org.libvirt.unix.monitor</code> for read-only access.
