The following changes introduce a new test-program //file-delete//, apart from the already existing 32 tests for `fc` "file-create" audit class which were introduced in D15286 and committed as rS334360. These 10 test cases check the proper audit of folllowing system calls
* rmdir(2)

Note: `open(2)` and `openat(2)` will be handled in a separate test-program.
