kselftests: cgroup: update kmem test precision tolerance

1813e51eece0 ("memcg: increase MEMCG_CHARGE_BATCH to 64") has changed
the batch size while this test case has been left behind. This has led
to a test failure reported by test bot:
not ok 2 selftests: cgroup: test_kmem # exit=1

Update the tolerance for the pcp charges to reflect the
MEMCG_CHARGE_BATCH change to fix this.
