memcg: use native word page statistics counters
The statistic counters are in units of pages, there is no reason to make
them 64-bit wide on 32-bit machines.
Make them native words. Since they are signed, this leaves 31 bit on
32-bit machines, which can represent roughly 8TB assuming a page size of
4k.
