[LTP] [PATCH] memcg/stat_test: Use more memory for tests

[Joerg Vehlow]

From: Joerg Vehlow <joerg.vehlow@aox-tech.de>

f0b9d187d increased the memory used by a lot of
memcg tests to 33*pagesize, because some counters in
memory.stat are only updated in batches of 32.
With kernel commit 766a4c19d this batching is also applied
to some more counters.

Use 33 * pagesize for all test now should make them pass
before and after this commit.

Fixes: #780
This should also fix part of #93 and #783
