[libvirt] [PATCH 2/2] libxl: set shadow memory for any guest type, not only HVM

[Marek Marczykowski-Górecki]

Otherwise starting PVH guest will result in "arch_setup_bootlate:
mapping shared_info failed (pfn=..., rc=-1, errno: 12): Internal error".

After this change the behaviour is the same as in `xl`.
