target-ppc/translate.c: Use ULL suffix for 64 bit constants

64 bit constants need the "ULL" suffix, not just "UL", because
on 32 bit platforms 'long' is not large enough and this will
cause a compiler warning.

PPC: sPAPR: Only use getpagesize() when we run with kvm

We currently size the msi window trap page according to the host's page
size so that we poke a working hole into a memory slot in case we overlap.

However, this is only ever necessary with KVM active. Without KVM, we should
rather try to be host platform agnostic and use a constant size: 4k.

This fixes a build breakage on win32 hosts.
