[LTP] [PATCH v2] testcases: fix file path to control access to cron

[Dan Rue]

Hello!

I noticed that this change did not make the last LTP release. Is there
any reason why it has not been merged?
- PR: https://github.com/linux-test-project/ltp/pull/169
- patch file: https://github.com/linux-test-project/ltp/commit/9900c9451e04c1e1e9ddb53a10eec84cc31e0dea.patch

I can follow up with a proper patch email if that is preferred.

Thanks!
Dan
