hvmloader: fix scratch_alloc to avoid overlaps

scratch_alloc() set scratch_start to the last byte of the current
allocation.  The value of scratch_start is then reused as is (if it is
already aligned) in the next allocation.  This result in a potential reuse
of the last byte of the previous allocation.
