[libvirt PATCH 7/9] qemu: add passtStateDir to qemu driver config

[Laine Stump <laine@xxxxxxxxxx>]

--

It seems a bit wasteful to allocate another string for this, since
it is 100% always ${stateDir}/passt, but everyone else is doing this
(e.g. slirpStateDir), so I'm just following along with the cult.
