[XEN] Pin l3 shadows of older x86_64 linux guests.
Older x86_64 linux kernels use one l4 table per cpu and context switch by
changing an l4 entry pointing to an l3 table.  If we're shadowing them
we need to pin l3 shadows to stop them being torn down on every
context switch.  (But don't do this for normal 64bit guests).
