The following changes add to the already existing 24 tests for `fc` "file-create" audit class which were introduced in D15286 and committed as rS334360. These 24 test-cases check the proper audit of `open(2)` and `openat(2)` for various modes in both success and failure mode.
Following modes were defined by the [audit events](https://github.com/openbsm/openbsm/blob/master/etc/audit_event#L93) list
* read - create
* write - create
* read - write - create
* read - create - trunc
* write - create - trunc
* read - write - create - trunc
