punybench: hogmem: try harder if we cannot allocate hogmem
Some systems have more physical memory than virtual address space
like certain Arm v7A systems with 4GB of physical memory but only 3GB
of virtual address space, and in these cases the hog function will try
to allocate more memory than possible. This changes the hog function
to back off at 1MiB increments.
BUG=chrome-os-partner:30913
TEST=kernel_fs_Punybench passes on a 4GB Nyan system
