In that case we should definitel split the 'virsh console' impl out into
a separate binary, so we can use the non-Xen specific codebase and stil
maintain your privilege separation.

Although we don't use the qemudGetSocketIdentity() anyway other than under
the POLKIT code, this may change in the future, so it'd just be convenient
to have a Solaris impl there. We can change the #if HAVE_POLKIT to be
#ifdef HAVE_POLKIT || __sun, so the method is available to the privilege
checking code too.
