            test if stress-ng can read+write+map /secretmem anon inodes

Recently, a regular kernel + stress-ng testing revealed that SELinux
prevents the stress-ng program from writing (syscall = ftruncate)
and reading (syscall = mmap) the /secretmem anon inodes. The TC
reproduces the situation.

In order to enable various stress-ng functions, I believe that SELinux
policy should allow the actions mentioned above. The TC looks for
appropriate policy rules and file context patterns.

The TC covers RHEL-116154 and RHELTEST-2022.
