[LTP] [PATCH] lib/default_cleanup: add default_cleanup() for old testcases

[Zhao Gongyi]

In some old testcases, cleanup() will not run since it exit
form tst_brk. For example, because of the calling of ltp_syscall
have no real cleanup when syscall not support, testcase ssetmask01
will leave tmp file.
