KVM: selftests: map Xen's shared_info page using HVA rather than GFN
Using the HVA of the shared_info page is more efficient, so if the
capability (KVM_XEN_HVM_CONFIG_SHARED_INFO_HVA) is present use that method
to do the mapping.
NOTE: Have the juggle_shinfo_state() thread map and unmap using both
GFN and HVA, to make sure the older mechanism is not broken.
