[PATCH] memblock test: Modify the obsolete description in README

[shaoqin . huang]

From: Shaoqin Huang <shaoqin.huang@xxxxxxxxx>

The VERBOSE option in Makefile has been moved, but there still have the
description left in README. For now, we use `-v` options when running
memblock test to print information, so also add some description about
it.
