A specific approach for the TST_FD_MEMFD_SECRET is probably required, 
because we don't really want to test EACCESS for all the other file 
descriptions. That might hide a bug in the kernel. We need to create a 
new test, since this one is only checking for EBADF/EINVAL according to 
the description.
