KVM: arm64: selftest: Add the missing .guest_prepare()

Running page_fault_test on a Cortex A72 fails with

Test: ro_memslot_no_syndrome_guest_cas
Testing guest mode: PA-bits:40,  VA-bits:48,  4K pages
Testing memory backing src type: anonymous
==== Test Assertion Failure ====
  aarch64/page_fault_test.c:117: guest_check_lse()

  guest_check_lse()

because we don't have a guest_prepare stage to check the presence of
FEAT_LSE and skip the related guest_cas testing, and we end-up failing in
GUEST_ASSERT(guest_check_lse()).

Add the missing .guest_prepare() where it's indeed required.
