[LTP] [PATCH] mtest05/mmstress: Fix failure on read-only system

[the_hoang0709@yahoo.com]

From: Hoang Nguyen <the_hoang0709@yahoo.com>

In order not to fail the test on read-only system, we used tst_tmpdir to
create temporary folder to run the test. Then remove it with tst_rmdir
after test finished (or test failed at the middle).

Fixes #87.
