Rob Bradford 99d9a3d299 vmm: memory_manager: Avoid MAP_PRIVATE CoW with VFIO for hugepages too ...

We can't use MAP_ANONYMOUS and still have huge pages so MAP_SHARED is
effectively required when using huge pages.

Unfortunately it is not as simple as always forcing MAP_SHARED if
hugepages is on as this might be inappropriate in the backing file case
hence why there is additional complexity of assigning to mmap_flags on
each case and the MAP_SHARED is only turned on for the anonymous file
huge page case as well as anonymous shared file case.
