Ian Klemm e8e532faf3 tests: exercise memory reserve on the hugepage UFFD restore zone ...

Turn reserve=on for the hugepage-backed memory zone in the UFFD
snapshot/restore integration test. Hugepages are the most likely place
to want reserve (an over-committed huge page pool is exactly the case
that otherwise SIGBUSes the guest), so this is the natural test to give
the option real coverage, as suggested in review.

It exercises the reserve mmap path twice: once on the source VM boot and
once on the demand-paged restore. The existing skip guard already
requires the 256 free 2MiB pages this zone needs, and the source VM is
killed before the restore VM is started, so reserving from the pool
never has to back two VMs at once.
