[LTP] [PATCH 6/6] ima: Use ima tcb policy files for test

[Jia Zhang]

In order to make all tests running smoothly, the policy files should
keep up with the default ima tcb policy. Especially ima_violations.sh
expects to have a func=FILE_CHECK with mask=MAY_WRITE to trigger open
writer and ToMtoU violations. Unfortunately, if ima_policy.sh
which would change the system IMA policy ran before ima_violations.sh,
ima_violations.sh would fail for sure because its prerequisite is broken.
