For the subject "[PATCH v2] ext4/004: add dump/restore test"
The seq number can be skipped for new test.

$restoredir should be rm'ed before running the test, as part of test
setup not cleanup, as Dave pointed out.
$dumpdir doesn't need cleanup, scratch dev will be recreated in next
test run, Dave pointed this out too.
Also the var names should be "$restore_dir" and "$dump_dir"

Just remove $restore_dir and restoresymtable, not other files, test
dev is supposed to be aged.
