[PATCH] ext4/004: add dump/restore test

[Xiaoguang Wang <wangxg.fnst@cn.fujitsu.com>]

This test case will first use fsstress to fill a file system, then
dump it to standard output and restore it from standard input, finally
check that the original contents and the new contents generated by
restore tool will be same.
