[libvirt] PATCH: Update XenD for new location of (localtime 1) SEXPR



Newer versions of XenD have the (localtime 1) bit of the SEXPR
moved outside the (image ...)  bit, and made available for both PV
and HVM guests. This patch updates our code to cope with this. For
compatability we also still put the (localtime 1) bit inside the
HVM (image ...) section too - its harmless on new XenD, and stops
us breaking old deployments. Finally, this also updates the XM 
driver to accept localtime=1 for PV guests.
